Directions (21-24):In each of the questions given below, four words have been highlighted. These four words may or may not have been placed in their correct positions. The sentence is then followed by options with the correct combination of words that should replace each other in order to make the sentence grammatically and contextually correct. Find the correct combination of the words that should replace each other. If the sentence is correct as it is, then select option (e) as your choice.

Harnessing the potential (A) of the digital revolution requires redefining (B) digital access that goes beyond physical connectivity (C) to share specific opportunities (D) available.

The correct option is No replacement required.

Let us analyze the given sentence contextually and grammatically to understand why no word replacement is needed:

Given sentence:
"Harnessing the potential (A) of the digital revolution requires redefining (B) digital access that goes beyond physical connectivity (C) to share specific opportunities (D) available."

1. Position (A) - potential:
The gerund "Harnessing" (meaning capturing or utilizing) correctly modifies the noun "potential" (meaning capability or possibilities). "Harnessing the potential" is a grammatically standard and contextually appropriate phrase.

2. Position (B) - redefining:
The sentence discusses changing how we understand or define "digital access". Therefore, the verb "redefining" fits perfectly after the main verb "requires".

3. Position (C) - connectivity:
"Physical connectivity" refers to the literal infrastructure and hardware links of the digital world. The word "connectivity" correctly functions as a noun following the adjective "physical".

4. Position (D) - opportunities:
"Specific opportunities" correctly describes the benefits or chances available through digital access. "Opportunities" acts as the noun object of the infinitive verb "to share".

Since all highlighted words are placed in their correct positions to convey a grammatically sound and meaningful thought, no words need to swap positions.
