Question

Choose the right option to fill the gap. Nahal ____ his PhD in trauma studies by December this year.

• A. will completing
• B. will have been completing
• C. will have completed
• D. will be completed

Hint:

Use \textbf{future perfect} whenever deadline with word \textbf{by} is given.

Answer 1

The Correct Option is C

Step 1: Focus on the time expression in the sentence. The phrase “by December” shows that the action will be completed before a specific point in the future. Such expressions indicate that the action will already be finished by that future deadline, which requires the future perfect tense.
Step 2: Recall the grammatical structure of the future perfect tense. It is formed using: will + have + past participle. Any correct option must follow this structure exactly.
Step 3: Analyze each option: - (A) — does not follow a correct future tense structure, so it is grammatically incorrect. - (B) — is in the future perfect continuous tense, which emphasizes duration or continuity rather than simple completion, making it unsuitable here. - (C) — correctly follows the structure will + have + past participle and matches the required meaning → correct. - (D) — uses a passive form that is not grammatically appropriate in this context, so it is incorrect.
