Step 1: Analyzing the sentences.
- Sentence 1: "She described about the journey" is incorrect. The correct phrasing is "She described the journey," as the preposition "about" is unnecessary.
- Sentence 2: "We are awaiting her reply" is correct. The sentence follows proper grammar and structure.
- Sentence 3: "She is superior to us" is correct. The sentence is grammatically sound and uses the correct comparative form.
- Sentence 4: "She requested for more time" is incorrect. The phrase "requested for" should be replaced by "requested more time."
- Sentence 5: "She is sharing with her friend" is incorrect. The sentence should be "She is sharing it with her friend," as "sharing" requires an object.
- Sentence 6: "She insisted for an apology" is incorrect. The correct form is "She insisted on an apology," as "insist" requires the preposition "on."
Step 2: Evaluating the options.
- (A) 2, 3, 5: This option includes grammatically correct sentences (2 and 3), so it is not the correct choice.
- (B) 1, 4, 6: All of these sentences are grammatically incorrect, making this the correct answer.
- (C) 1, 2, 5: Sentence 2 is correct, so this is not the right choice.
- (D) 1, 3, 4: Sentence 3 is correct, making this option incorrect.
- (E) 2, 4, 5: Sentence 2 is correct, so this is not the correct option.
Step 3: Conclusion.
The correct answer is (B) 1, 4, 6, as these sentences are grammatically incorrect.
