Which of the following best describes 'ephemeral'?

The term "ephemeral" refers to something that is short-lived or transient, capturing the idea of being fleeting. This word is often used to describe experiences, events, or objects that do not last long and are here today but gone tomorrow. For instance, certain flowers bloom for just a day, or digital content might be available for only a short period. The essence of "ephemeral" reflects the temporary nature of whatever is being described, making "fleeting" the most accurate characterization among the choices provided. The other options, such as "long-lasting," "permanent," and "stable," all imply durability or endurance, which directly contrasts with the concept of ephemerality.
