The correct option is speaking activity.

Explanation:

In language teaching, an activity where learners work in pairs with slightly different pictures and must ask each other questions to find the differences is known as an information gap activity, which primarily serves as a speaking activity.

Here is a breakdown of why this is a speaking activity:

1. Verbal Interaction: Learners cannot simply look at each other's pictures; they are required to describe their own images and ask clarifying questions (e.g., "Is there a cat under the table in your picture?").

2. Communication Goal: The primary objective is to convey information orally to complete a shared task, fostering fluency, vocabulary usage, and conversational skills.

Therefore, this pair task is classified as a speaking activity.
