Fill in the blanks in the following sentence by choosing the correct options out of the given ones.
He looked ________ his watch ________ his bedroom.

Correct option is B

Correct option: (b) for ; in
Meaning-based explanation (highlight):
• look for = to search/try to find something (Hindi: ढूँढना / तलाश करना)
• in the bedroom = location/place (Hindi: शयनकक्ष में)
Correct sentence: He looked for his watch in his bedroom.
Grammatical Rule (English):
• “look for” is a fixed verb-preposition combination meaning “search”.
• “in” is used for enclosed places/rooms (in a room/bedroom).
व्याकरणिक नियम (Hindi):
• “look for” का अर्थ तलाश करना होता है (fixed combination)।
• “in” का प्रयोग कमरे/स्थान के अंदर होने के लिए होता है।
Why other options are incorrect:
• (a) “at; at” → “in the bedroom” के लिए “at” सामान्यतः गलत/कम उपयुक्त है।
• (c) “in; at” → “look in” = अंदर झाँकना; watch के साथ intended meaning नहीं बनता।
• (d) “on; through” → “look on” = दर्शक बनकर देखना; “through” यहाँ गलत है।
Hence, option (b) is the correct answer.
