Each question is divided into four parts where one of the parts may or may not contain an error. Choose the partthat has the error as your answer. If allthe parts are correct choose

“No Error”.

The speaker delivered her (A)/ presentation so confident that the (B)/ entire audience was captivated by her words, (C)/ nodding in agreement and appreciation. (D)

The correct option is B.

Step-by-step Explanation:
1. Analyze the Sentence Structure: The sentence describes the manner in which the speaker performed the action of delivering her presentation.
2. Identify the Error in Part B: The phrase "so confident" uses the adjective "confident". However, this modifier is describing the verb "delivered" (how the speech was delivered), not the speaker or the presentation directly.
3. Apply the Grammatical Rule: Verbs must be modified by adverbs, not adjectives. Therefore, the adjective "confident" must be replaced with the adverb "confidently".
4. Corrected Sentence: "The speaker delivered her presentation so confidently that the entire audience was captivated by her words..."
5. Conclusion: Since "confident" is grammatically incorrect in this context, the error lies in part (B).
