Which of the following phrases given below the sentence can replace the words /phrase given in bold in the sentence grammatically and meaningfully?

The team of researchers was preparing for the field study, which is scheduled to begin next month.

1. were preparing for
2. is preparing for
3. has prepared for

Option B is the correct answer. Both phrases, 2 and 3, could replace the given phrase.

Phrase 1: "were preparing for" is incorrect, as "team" is a collective noun, treated as singular, so "was" is correct.

Phrase 2: "is preparing for" fits because it implies that the team is currently preparing, which aligns with the ongoing nature of the scheduled study. It uses the present continuous tense, which is appropriate for actions that are ongoing or happening in the near future. Since the field study is scheduled for next month, this tense fits if the preparation is currently taking place.

Phrase 3: "has prepared for" fits because it suggests the team has already completed its preparation, which is also valid in a different context. it uses the present perfect tense, which is suitable for actions completed in the past with relevance to the present situation. If the team has already completed its preparation for the study that begins next month, this phrase would be a valid choice.
