Ellis Pike is built to act the part of the lawyer in the film.

The correct answer is is built.

Ellis Pike is built to act the part of the lawyer in the film.

Note: While 'is built' might seem unusual in this context, it grammatically fits the sentence structure if 'Ellis Pike' refers to a physical structure or a character created for a specific purpose. If 'Ellis Pike' is a person, 'is cast' or 'is chosen' would be more common. However, based on the provided options and sentence structure, 'is built' is the most fitting choice.

Explanation: The sentence is in the present passive voice. 'Ellis Pike' is the subject, and the action of being 'built' (created, designed, or cast) is being done to it.
