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).

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.

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

To determine the correct arrangement of the bold words, let us analyze the context and grammatical structure of the sentence:

1. Looking at the phrase "Indian telecom operators have making (A)...":
The present perfect auxiliary verb "have" requires a past participle verb form (V3). The present participle "making" is grammatically incorrect after "have" here. However, the word "surpassed (B)" is in past participle form and logically fits the phrase: "have surpassed the three-year 5G network rollout target".

2. Looking at the next part of the sentence: "...and are now surpassed (B) efforts...":
The phrase "are now" requires a present participle (V-ing form) to show an ongoing activity. Replacing "surpassed" with "making" gives: "and are now making efforts...", which is grammatically sound and meaningful.

3. Checking words (C) and (D):
- "enhance (C)" fits correctly after the infinitive marker "to" ("to enhance adoption...").
- "segments (D)" correctly functions as a noun following the adjective "key" ("across various key segments").

Therefore, interchanging word (A) with word (B) restores both grammatical correctness and logical meaning to the sentence.

Corrected Sentence:
"Indian telecom operators have surpassed the three-year 5G network rollout target and are now making efforts to enhance adoption of 5G applications across various key segments."
