In the question below, four words are given in bold, which may not be arranged in the correct order. Choose the replacement needed between the words to make the sentence correct and meaningful.

Indian telecom operators have making (A) the three-year 5G network rollout target and are now surpassed (B) efforts to enhance (C) adoption of 5G applications across various key segments (D).

Correct option is A

The correct answer is (A) Only (A)-(B).

Step-by-Step Analysis

To find the correct order, we need to look at the verb tenses and the logic of the sentence:

1. Position (A): The sentence uses the auxiliary verb "have." In English, "have" must be followed by a past participle to form the present perfect tense. "Making" (a present participle) is grammatically incorrect here. "Surpassed" (B) fits perfectly: "have surpassed the three-year 5G network rollout target."
2. Position (B): The sentence uses the auxiliary verb "are now." This requires a present participle (-ing form) to show an ongoing action. "Making" (A) fits here: "and are now making efforts to..."
3. Position (C): The word "enhance" is an infinitive verb (to + enhance). It correctly describes the goal of the efforts—to improve or increase adoption.
4. Position (D): The word "segments" is a noun referring to different sectors of the market. This is the standard term used in the telecom industry (e.g., "market segments").

The Logical Replacement

• A ↔ B: Swap the past participle "surpassed" with the present participle "making" to satisfy the rules of Present Perfect and Present Continuous tenses.

Corrected Sentence

Indian telecom operators have surpassed (B) the three-year 5G network rollout target and are now making (A) efforts to enhance (C) adoption of 5G applications across various key segments (D).

Grammar Rule: Auxiliary Verb Agreement

Understanding which verb form follows an auxiliary is key to solving these "word swap" questions:

• Have/Has/Had + Past Participle (e.g., surpassed) = Perfect Tense
• Is/Am/Are/Was/Were + Present Participle (e.g., making) = Continuous Tense
