Locate the Subject in the following sentence :

While working in the bank, she learnt a lot about beneficial investments.

Correct option is B

The correct subject in the sentence is (b) she.

Explanation:
The subject of a sentence is the person, place, thing, or idea that performs or is described in the action. Here, "she" is the subject performing the action "learnt." The phrase "while working in the bank" is a subordinate clause providing context, not the subject.

Grammatical rule used: The subject is the noun or pronoun performing the main action of the verb in the independent clause.
Explanation of the rule in Hindi: मुख्य वाक्य में क्रिया (verb) का कार्य करने वाले व्यक्ति या वस्तु को वाक्य का कर्ता (subject) कहते हैं।

Example:

Meanings of other options:
· while working in the bank: Subordinate clause giving background information.
· learnt: (सीखा) Verb describing the action, not the subject.
· about beneficial investments: Prepositional phrase acting as the object, not the subject.
