The correct option to fill in the blank is dangling.

The word "dangling" means "hanging or swinging loosely". It is the most accurate word to describe legs that are resting in the water.

The other options are incorrect.

• Remaining means "still existing, present". It is not the correct word to use in this sentence because the legs are not remaining in the water, they are dangling in the water.
• Swimming means "to move through the water by moving the body or parts of the body". It is not the correct word to use in this sentence because the legs are not swimming, they are dangling in the water.
• Washing means "to clean something with water". It is not the correct word to use in this sentence because the legs are not washing, they are dangling in the water.
