[ alt="03.01.2019.30401" src="//storage.googleapis.com/tb-img/production/19/01/03.01.2019.30401.PNG">

In option 1,

[ alt="03.01.2019.30402.3" src="//storage.googleapis.com/tb-img/production/19/01/03.01.2019.30402.3.PNG" style="width: 46px; height: 44px;"> and [ alt="03.01.2019.30402.4" src="//storage.googleapis.com/tb-img/production/19/01/03.01.2019.30402.4.PNG" style="width: 45px; height: 45px;"> are not opposite to each other.

Hence, the cube given in option 1 cannot be made based on the unfolded cube in the question figure.

Option 2 :

If we consider faces with “[ alt="SSC CHSL 25 March 2018 Shift3 Bhagwant Umang Pratap Singh Reviewed (1) images q24e" src="//storage.googleapis.com/tb-img/production/18/09/SSC_CHSL_25_March_2018_Shift3_Bhagwant_Umang_Pratap_Singh%20Reviewed%20%281%29_images_q24e.PNG" style="height:32px; width:33px">” as centre and fold its surrounding faces inside,

we find that face with “[ alt="SSC CHSL 25 March 2018 Shift3 Bhagwant Umang Pratap Singh Reviewed (1) images q24f" src="//storage.googleapis.com/tb-img/production/18/09/SSC_CHSL_25_March_2018_Shift3_Bhagwant_Umang_Pratap_Singh%20Reviewed%20%281%29_images_q24f.PNG" style="height:20px; width:19px">” and “[ alt="SSC CHSL 25 March 2018 Shift3 Bhagwant Umang Pratap Singh Reviewed (1) images q24g" src="//storage.googleapis.com/tb-img/production/18/09/SSC_CHSL_25_March_2018_Shift3_Bhagwant_Umang_Pratap_Singh%20Reviewed%20%281%29_images_q24g.PNG">” are opposite to each other,

faces with “[ alt="SSC CHSL 25 March 2018 Shift3 Bhagwant Umang Pratap Singh Reviewed (1) images q24h" src="//storage.googleapis.com/tb-img/production/18/09/SSC_CHSL_25_March_2018_Shift3_Bhagwant_Umang_Pratap_Singh%20Reviewed%20%281%29_images_q24h.PNG" style="height:31px; width:31px">” and “[ alt="SSC CHSL 25 March 2018 Shift3 Bhagwant Umang Pratap Singh Reviewed (1) images q24i" src="//storage.googleapis.com/tb-img/production/18/09/SSC_CHSL_25_March_2018_Shift3_Bhagwant_Umang_Pratap_Singh%20Reviewed%20%281%29_images_q24i.PNG" style="height:34px; width:35px">” are opposite to each other

and faces with “[ alt="SSC CHSL 25 March 2018 Shift3 Bhagwant Umang Pratap Singh Reviewed (1) images q24e" src="//storage.googleapis.com/tb-img/production/18/09/SSC_CHSL_25_March_2018_Shift3_Bhagwant_Umang_Pratap_Singh%20Reviewed%20%281%29_images_q24e.PNG" style="height:32px; width:33px">” and “[ alt="SSC CHSL 25 March 2018 Shift3 Bhagwant Umang Pratap Singh Reviewed (1) images q24j" src="//storage.googleapis.com/tb-img/production/18/09/SSC_CHSL_25_March_2018_Shift3_Bhagwant_Umang_Pratap_Singh%20Reviewed%20%281%29_images_q24j.PNG" style="height:36px; width:35px">” are opposite to each other.

Here, the cube in option 2 of the answer figure cannot be made based on the unfolded cube in the question because faces with “[ alt="SSC CHSL 25 March 2018 Shift3 Bhagwant Umang Pratap Singh Reviewed (1) images q24e" src="//storage.googleapis.com/tb-img/production/18/09/SSC_CHSL_25_March_2018_Shift3_Bhagwant_Umang_Pratap_Singh%20Reviewed%20%281%29_images_q24e.PNG" style="height:32px; width:33px">” and “[ alt="SSC CHSL 25 March 2018 Shift3 Bhagwant Umang Pratap Singh Reviewed (1) images q24j" src="//storage.googleapis.com/tb-img/production/18/09/SSC_CHSL_25_March_2018_Shift3_Bhagwant_Umang_Pratap_Singh%20Reviewed%20%281%29_images_q24j.PNG" style="height:36px; width:35px">” are opposite to each other which is shown adjacent in option 2.

Hence, option 2 is the correct alternative.
