Final answer:
The correct synonym for 'aesthetic' in the given context is 'artistic', which pertains to the appreciation of beauty or appearance.
Step-by-step explanation:
The synonym of aesthetic in the given sentence is artistic. Aesthetic refers to the appreciation of beauty or good taste and is primarily concerned with beauty, artistic impact, or appearance. It is not synonymous with displeasing or unattractive, which have negative connotations and refer to the lack of beauty or appeal. Instead, aesthetic is derived from the Greek “aisthetikos,” meaning esthetic, sensitive, or sentient, and entails a more intuitive, sensory contemplation of beauty, regardless of an object's practical function. In art, this can translate to an aesthetic experience that is a response to an object's representational qualities, capable of inspiring feelings of awe and wonder.
