The answer is the first one: processing and experiencing of emotion.

Explanation for each option:

1. Processing and experiencing of emotion: This is correct. The limbic system is a complex set of structures in the brain that is primarily responsible for our emotional life and has a lot to do with the formation of memories. It plays a key role in processing and experiencing emotions.

2. Bending over backwards: This is incorrect. Bending over backwards is a physical action related to the musculoskeletal system, not the limbic system.

3. Perception of language: This is incorrect. The perception of language is primarily associated with areas like Wernicke's area in the brain, not the limbic system.

4. Expression of language: This is incorrect. The expression of language is mainly associated with Broca's area in the brain, not the limbic system.

5. Retrieving memories from a long time ago: This is partially correct, as the limbic system, particularly the hippocampus, is involved in memory formation. However, the question specifically asks about the primary function, which is more closely related to emotion.

In summary, the limbic system is most directly involved in the processing and experiencing of emotion.
