Answer: artístico
Step-by-step explanation:
"artístico" is a derived masculine adjective that comes from the word art with the suffix "-istico"
"artística" is a derived feminine adjective that comes from the word art with the suffix "-istica"
Its meaning is something that is done with art or good taste.
Since it is an adjective, it must agree in gender and number with the noun it describes, so depending on whether the noun is masculine or feminine we must use "artístico" or "artística"
