Choose the correct option to complete the sentence given below. In case no option is correct, choose “None of the above”.
______ he was sleeping, the enemy entered the house.

Correct option is C

The correct option is (c).

• Explanation: The sentence refers to an action happening during the time another action was in progress. While is the most appropriate conjunction to show that one action took place during another continuing action.
• Correct answer word – While
  Hindi meaning: जबकि / जब
  Example: While she was studying, her brother was playing.
• Grammar Rule involved: While is used to connect two actions happening at the same time, especially when one action is in progress.
• Meanings of other options:
  • When – at the time that (जब)
  • Whereas – in contrast, while on the other hand (जबकि / इसके विपरीत)

So the correct answer is (c)
