EPHEMERAL:

The correct answer is A. Passing.

Ephemeral means lasting for a very short time. It is often used to describe things that are beautiful or enjoyable, but that will not last long. For example, a flower that blooms for only a few days is ephemeral.

The other options are incorrect because they do not accurately describe the meaning of the word ephemeral.

• Sensuous means relating to the senses, especially the sense of touch.
• Permanent means lasting or intended to last for a long time.
• Distasteful means unpleasant to taste or smell.
