The correct option to fill in the blanks in the sentence “… a good film. Wasn’t it?” is It was. So, the completed sentence is: “It was a good film. Wasn’t it?”

Here’s why:

• A. It is: This option is incorrect because “is” is used for present tense, and the question “Wasn’t it?” is in the past tense. The tenses should match in this context.

• B. Was it: This option is incorrect because it doesn’t form a complete sentence before the question “Wasn’t it?”.

• C. There is: This option is incorrect because “There is” is used when introducing or identifying something. In this context, we are commenting on the film, not introducing it.

• D. It was: This is the correct option. “It was” is used to refer to a situation or condition in the past, which fits with the past tense question “Wasn’t it?”.

• E. There was: This option is incorrect because “There was” is typically used to indicate that something existed or happened in the past. In this context, we are commenting on the quality of the film, not its existence.
