Justifiably criticized

Explanation:

The passage is an excerpt from Etiquette, by Emily Post.

The phrase "often condmned and often very deservedly" can best be explained as justifiably criticized in the excerpt.

The other options, "carefully scrutinzed", "undeniably improper", and "thoroughly convincing" are either completely off the conveyed meaning of the underlined phrase or are not as close in meaning to it as the correct option B.
