The question asks to identify the correct statements about the sentence: ‘Mani wants Meera to eat her lunch on time.’ We need to analyze the grammatical roles of the noun phrases (NP) and clauses within this sentence.

Analyzing Sentence Structure

The main structure is: Subject (Mani) + Verb (wants) + Complement.

The complement of the verb 'wants' is the entire infinitive clause: ‘Meera to eat her lunch on time’.

Evaluating Option 1: NP ‘Meera’ as Complement

Statement: The NP ‘Meera’ is a complement of the verb ‘wants.’

Analysis: While 'Meera' is related to 'wants', it functions specifically as the subject of the infinitive clause 'to eat her lunch on time'. It is not a direct object or complement in the same way 'a book' would be in 'Mani wants a book'.

Result: Incorrect.

Evaluating Option 2: NP ‘Meera’ as Subject of Non-Finite Clause

Statement: The NP ‘Meera’ is the subject of the non-finite clause.

Analysis: The non-finite clause here is the infinitive clause 'to eat her lunch on time'. The action 'to eat' is performed by 'Meera'. Therefore, ‘Meera’ is the subject of this non-finite clause.

Result: Correct.

Evaluating Option 3: Clause as Complement of Verb ‘wants’

Statement: The clause ‘Meera to eat her lunch on time’ is the complement of the verb ‘wants’.

Analysis: The verb 'wants' requires something to specify what Mani wants. The entire infinitive clause ‘Meera to eat her lunch on time’ fulfills this role, acting as the complement of the main verb ‘wants’.

Result: Correct.

Evaluating Option 4: NP ‘her lunch’ as Object of Verb ‘eat’

Statement: The NP ‘her lunch’ is not the object of the verb ‘eat’.

Analysis: Within the infinitive clause, 'to eat' is the verb, and 'her lunch' is the thing being eaten. Thus, ‘her lunch’ is the direct object of the verb ‘eat’.

Result: Incorrect.

Conclusion

The correct statements are 2 and 3.
