Read the following sentence carefully and check each part for error. Mark the option that indicates the error.
To see a crow eating a piece of bread, a fox thought how it could trick that fellow.

Correct option is A

The error lies in option (a).

• Explanation: The phrase “To see a crow eating…” is incorrect because the infinitive phrase wrongly suggests that the fox performed the action with a purpose. Here, the intended meaning is that on seeing or seeing the crow, the fox thought of tricking it. Thus, the opening construction is faulty.
• Correct sentence: Seeing a crow eating a piece of bread, a fox thought how it could trick that fellow.
• Grammatical rule (English): An infinitive phrase of purpose should not be used when the meaning is simply “on seeing” or “after seeing”. A participial phrase is more appropriate here.
• व्याकरण नियम (Hindi): यहाँ to see का प्रयोग उद्देश्य नहीं बताता। इसलिए seeing या on seeing का प्रयोग अधिक उपयुक्त है।

So the correct answer is (a)
