Find the correct sentence structure to complete the statement: "I want Ramesh and "

The pronoun follows the verb 'want', making it the object of the sentence. Therefore, the objective case 'her' must be used instead of the nominative case 'she'. Additionally, since there are two people (Ramesh and her), the plural noun 'captains' is required.

Step-by-step Derivation:
Step 1: Identify the grammatical role of the pronoun. In the sentence 'I want [someone]', the [someone] is the direct object of the verb 'want'.
Step 2: Determine the correct pronoun case. For the third-person singular feminine, the nominative case is 'she' and the objective case is 'her'. Since it is an object, 'her' is correct. This eliminates options B and D.
Step 3: Evaluate the complement. The phrase 'to be' is the standard infinitive construction following 'want' (want someone to do something). Option C uses 'as', which is less idiomatic in this specific structure ('want X as Y' is possible, but 'want X to be Y' is the standard for designating a role/state).
Step 4: Check for number agreement. Since the subject group consists of two people (Ramesh and her), the noun must be plural. 'Captains' is correct. Option B uses 'captain' (singular), which is incorrect.
Step 5: Conclusion: Option A ('her to be the captains...') satisfies both the objective case requirement and the plural agreement.
