Amir Khan . . . . . new movie next year.

Answer: Option D

The sentence is: "Amir Khan . . . . . new movie next year."

We are talking about a planned or predicted action in the future. The correct and grammatically appropriate form here is "will release", which uses the structure:
Subject + will + base verb

So, the complete sentence should read:
"Amir Khan will release new movie next year."

This structure expresses a definite future action, which is what the sentence requires.

Why the other options are incorrect:
Option A: is release – This is incorrect because "is" must be followed by a present participle (verb+ing), not the base form. The correct form would be "is releasing" if we were talking about a scheduled future action using present continuous.
Option B: will be release – This is grammatically incorrect. If we were using passive voice, it should be "will be released." But in the active voice, "will be release" is incorrect.
Option C: going to release – This is missing the correct auxiliary verb "is." It should be "is going to release." Without "is," it is grammatically incomplete.

Conclusion:
The correct answer is will release because it correctly expresses a future action in the active voice using proper grammar.
