Fill in the blank to complete the sentence:-

The way they weave carpets in this region is not _____ to the way they are made in the neighboring state.

dissimilar

The correct answer is Option (4) → dissimilar

Dissimilar (Adjective) means not similar or alike. When used with "not" and followed by the preposition "to", it creates the phrase "not dissimilar to," which is idiomatic and means "very similar to" or "much the same as."
