Correct option is A
The error lies in option (a).
Explanation:
- The phrase enlarged numbers is incorrect because enlarge means to make bigger in size, not to indicate quantity in this context.
- To describe a high quantity, we use large numbers or a large number.
Correct sentence (one correct form):
- In 1914 Enfield supplied large numbers of motorcycles to the British War Department and also won a motorcycle contract for the Imperial Russian Government.
Grammatical rule (English):
- Use adjective large for quantity (large number of), not “enlarged” which refers to size expansion.
व्याकरण नियम (Hindi):
- मात्रा/संख्या बताने के लिए large number of प्रयोग होता है; “enlarged” का अर्थ आकार बढ़ाना होता है, संख्या नहीं।
So the correct answer is (a)
