Which word describes something that is country-like or simple?

The word that best describes something that is country-like or simple is "rustic." This term is often associated with the charm and simplicity of rural life, conveying an image of a natural, unrefined, and traditionally country aesthetic. Rustic items or styles often evoke feelings of warmth, nostalgia, and a connection to nature, reflecting environments that are less influenced by urban development or modern technology.

The other options do not convey this meaning: "urban" refers to something related to cities or town life, which is often more complex and fast-paced; "modern" indicates contemporary styles that may embrace sleekness and sophistication; "industrial" is associated with manufacturing and mechanization, which doesn't align with the simplicity and country-like quality suggested by "rustic."
