Correct Answer:
A. I
The subject of a sentence is the person, place, thing, or idea that performs the action. In the sentence "I met a beggar on the road.", the pronoun "I" performs the action of meeting, so it is the subject.
Sentence Structure:
- Subject: I
- Verb: met
- Object: a beggar
- Prepositional Phrase: on the road
Why the other options are incorrect:
- Met: This is the verb, not the subject.
- Beggar: This is the object (receiver of the action), not the subject.
- Road: This is part of the prepositional phrase indicating location.
