B) instructs us to greet friends and acquaintances with warmth and respect.

Explanation: one of the most common uses of a colon, is to introduce a list of elements (for example: I have three sisters: Mary, Jane and Sophie), but we must never use a colon (or any punctuation mark) to separate a verb or a preposition from their objects, so that is the mistake in the given sentence, it uses a colon between "to" (a preposition) and the lists of elements (the object of a preposition). So the correct sentence would be "Western etiquette instructs us to greet friends and acquaintances with warmth and respect, refrain from insults and prying curiosity, offer hospitality equally and generously to our guests."
