From the figure we can conclude:

1) The face of dice with star will be opposite to the side with a dot.

2) The side with plus will be opposite the side with a cross and square.

3) The side with circle will be opposite to the side with a hexagon.

Here in the figure above side with plus and the side with a cross and square are adjacent to each other.

Hence, it cannot be made based on the unfolded cube in the question figure.

Option 2 :

Option 2 cannot be formed, as if the cross line face appears in the front then the square shape face and the hexagon cannot be adjacent to it.

Option 2 :

The faces opposite to each other is shown below:

2) [ alt="F1 V.K.G D.K 12.09.2019 D1" src="//storage.googleapis.com/tb-img/production/19/09/F1_V.K.G_D.K_12.09.2019_D1.png" style="width: 114px; height: 115px;"> → This cube cannot be formed as  [ alt="F1 Pooja S 27-10-21 Savita D26" src="//storage.googleapis.com/tb-img/production/21/10/F1_Pooja%20S_27-10-21_Savita_D26.png" style="width: 41px; height: 41px;">and [ alt="F1 Pooja S 27-10-21 Savita D27" src="//storage.googleapis.com/tb-img/production/21/10/F1_Pooja%20S_27-10-21_Savita_D27.png" style="width: 41px; height: 41px;"> faces is opposite faces and no two opposite faces can appear together on the same dice.

3) [ alt="25.07.2018.0014" src="//storage.googleapis.com/tb-img/production/18/07/25.07.2018.0014.PNG"> → This cube can be formed as no two opposite faces appear together on the same

Hence, ‘option 2’ is the correct answer.
