Question

conspicuous means :

marked by skill in deception

without any attempt at concealment

causing inconvenience

lasting for a markedly brief time

Explanation:

The word "conspicuous" means easily seen or noticeable. "Without any attempt at concealment" aligns with this as something that is not hidden would be noticeable. "Marked by skill in deception" is more related to being deceitful (like "cunning"), "causing inconvenience" is about being a nuisance, and "lasting for a markedly brief time" is about duration (like "ephemeral").

Answer:

without any attempt at concealment
