Explanation:

- Power: It usually refers to the ability or capacity to do something or act in a particular way.

- Option 1 - Immunity: This refers to protection or exemption from something, not directly the opposite of power.

- Option 2 - Disability: This is a condition that may limit a person's movements, senses, or activities. It suggests a lack of ability, which aligns with being the opposite of power in some contexts.

- Option 3 - Liability: This refers to being responsible for something, especially by law. It doesn't imply a lack of power.

- Option 4 - None of these: Suggests no correct option.

The most suitable opposite for power here is disability.

- Correct Answer: Option 2 - Disability
