Correct Answer: Flexible

Solution : The correct choice is the fourth option.

Explanation: Rigid refers to being stiff, inflexible, or resistant to change. The antonym, therefore, should convey the opposite meaning of being adaptable and easily bending or changing. Flexible is the appropriate choice, as it signifies the ability to adjust, adapt, or bend without breaking.

Therefore, the correct antonym is, flexible.

The meanings of the other options are as follows:

• Superior : This term refers to something that is higher in rank, quality, or position.
• Distaste : This term refers to a feeling of dislike or aversion.
• Satiation : This term refers to the state of being satisfied or full.
