Question

In the given passage, a sentence is highlighted and divided into four parts. Identify the segment that contains an error, if any.

**Sentence:**
"It has not only improved the education(A)/ and learning process during the Covid-19 period, (B)/yet has also helped in introduction of numerous(C)/ fresh concepts and inventions in the field (D)."

**Options:**

Accepted Answer

**Solution:**

1. The sentence uses the correlative conjunction "not only ... but also" to connect two related ideas.

2. In part (C), the word "yet" is incorrectly used. The correct conjunction to pair with "not only" is "but also".

3. Therefore, "yet" should be replaced with "but" to maintain grammatical correctness and proper emphasis.

4. The corrected phrase should read: "It has not only improved the education and learning process during the Covid-19 period, but also has helped in introduction of numerous fresh concepts and inventions in the field."

**Answer:** (C)
