Which of the following should be the FIRST sentence after rearrangement?

The correct option is C.

To form a coherent and logically structured paragraph, let's analyze the given sentences step-by-step:

1. Sentence (c): "In today's digital era, the disparity in communication technology usage between young teenagers and their elderly grandparents has grown significantly."
This sentence serves as an ideal introductory sentence because it sets the broader context and introduces the primary subject of discussion: the growing technological gap between teenagers and their grandparents.

2. Sentence (b): "The primary obstacle of this technological divide is that both generations find it challenging to comprehend each other's preferred mode of expression."
This follows (c) by elaborating on the specific problem created by the "technological divide" introduced in sentence (c).

3. Sentence (e): "Because of these differing digital habits, grandparents often struggle to stay connected with their grandchildren's daily activities."
This sentence expands on the consequence of the communication challenge mentioned in (b).

4. Sentence (d): "Although this division can lead to feelings of isolation, the potential benefits of bridging this gap are substantial."
This acts as a transitional sentence, acknowledging the negative effect (isolation) while pivoting toward positive solutions.

5. Sentence (a): "Indeed, when teenagers teach seniors how to navigate digital platforms, it fosters mutual respect and strengthens family bonds."
This sentence concludes the paragraph by illustrating a concrete benefit of bridging the gap.

The logical sequence of the paragraph is (c) -> (b) -> (e) -> (d) -> (a).

Therefore, the FIRST sentence after rearrangement is sentence (c), which corresponds to Option C.
