Choose the correct option to complete the sentence given below. In case no option is correct, choose “None of the above”.
He opened the box only ______ it empty.

Correct option is C

The correct option is (c).

• Explanation: The sentence expresses purpose followed by result. The structure “only to find” is a standard English expression used when an action leads to an unexpected or disappointing result.
• Correct answer word – to find
  Hindi meaning: पता लगाना / यह जानना
  Example: He rushed to the station only to find that the train had left.
• Grammar Rule involved: The infinitive to find is used after only in this pattern to indicate the consequence of the earlier action.
• Meanings of other options:
  • open – not suitable grammatically in this structure (खुला / खोलना)
  • finding – participle form; does not fit the fixed expression here (पाते हुए)

So the correct answer is (c)
