Observing advantage (A)has become (B)the biggest digitalization (C)in India in the last (D)two years.

In the question below, four words are highlighted, which may not be correctly placed. Choose the correct replacement in between the highlighted words that can give appropriate meaning to the sentence.

The correct option is Only (A)-(C).

Step-by-Step Explanation:

1. Analyze the original sentence:
"Observing advantage (A) has become (B) the biggest digitalization (C) in India in the last (D) two years."
In the given sentence, the positions of the highlighted words "advantage" (A) and "digitalization" (C) make the sentence contextually illogical. "Digitalization" refers to a process or phenomenon, whereas "advantage" refers to a benefit.

2. Determine the correct positions:
Swapping word (A) advantage with word (C) digitalization changes the phrase "Observing advantage" to "Observing digitalization" (the process being observed) and "the biggest digitalization" to "the biggest advantage" (the benefit derived).

3. Evaluate the swapped sentence:
"Observing digitalization has become the biggest advantage in India in the last two years."
This sentence makes complete sense grammatically and contextually.

Therefore, swapping only (A)-(C) provides the appropriate meaning to the sentence.
