In the following question, some parts of the sentence may contain an error. Find out which part of the sentence does not have an error and click the option corresponding to it. If you think all the parts contain an error, mark option 5, i.e. ‘None of these’ as your answer choice. A Apple store in Amsterdam was evacuated and temporarily (A)/ closed after a iPad's battery exploded on Sunday. (B)/ Apple employees at the store secure the iPad and (C)/ punctured the battery in a container of sand after it exploded.  (D) ?

Option 4 : D

The correct answer is option 4, i.e. D since it is the part of the sentence which does not contain any error.

• In A, ‘A’ is incorrect and must be replaced with ‘An’. ‘An’ is used before the words starting with a vowel sound and ‘Apple’ starts with a vowel sound thus, ‘A’ must be replaced with ‘An’.
• In B also, ‘a’ before ‘iPad's’ must also be corrected because of the same reason.
• In C, ‘secure’ must be replaced with ‘secured’. As from the given context, we understand that the given sentence is in past tense, thus, it must also be corrected and ‘secure’ must be replaced with ‘secured’.
   

As only D part is the one that does not contain any error, thus, the correct answer choice is option 4.

The sentence can be correctly rewritten as-

An Apple store in Amsterdam was evacuated and temporarily closed after an iPad's battery exploded on Sunday. Apple employees at the store secured the iPad and punctured battery in a container of sand after it exploded.
