In the sentence pattern for asking questions, the subject is placed immediately after the operator (Operator [did, does, was] + Subject) while in the sentence pattern for making statements, the subject is placed before the verb phrase (Subject + VP). However, some statements may be in question form (You've already eaten?) and some questions (such as rhetorical ones) may be in statement form (Haven't you peed already?).
The answer is B, movie. "Action" is used as an adjective here, so it cannot be an object when there is no noun present. "Saw" is a verb. "I" is the subject, so the only remaining option is B, movie. The question to easily determine what the object is would be "What did you see?" And the answer would be "A movie".
