Step 1: Understanding the Question.
The sentence is "The shopkeeper sells lemons." We need to find what part of the sentence the word "lemons" plays.
Step 2: Key Concept.
A simple sentence has a subject, a verb, and often an object. The subject is who or what does the action. The verb names the action. The object is the person or thing that receives the action of the verb.
Step 3: Detailed Explanation.
In "The shopkeeper sells lemons," the word "shopkeeper" is the subject, since the shopkeeper is the one doing the selling. The word "sells" is the verb, since it names the action. The word "lemons" comes right after the verb and names what is being sold, so it receives the action of "sells." This makes "lemons" the object of the sentence.
It is not the subject, since the subject here is "shopkeeper," not "lemons." It is not the verb, since "sells" is the only action word in the sentence. It is not the predicate either, because the predicate is the whole part of the sentence that tells us what the subject does, which is "sells lemons," not the single word "lemons."
Step 4: Final Answer.
The word "lemons" receives the action of selling, so it is the object of the sentence. Hence, the correct option is (A).
