What this topic is really about
The sentence in option C is grammatically correct because it uses the auxiliary verb 'does' with the base form of the verb 'know' for a third-person singular subject. Option B is incorrect because 'knows' is a double-marking of the third-person singular, which is redundant after 'doesn't'. Option A is incorrect because 'don't' is grammatically incompatible with the singular pronoun 'he'.
The standard English spelling of the word is 'Accommodation', which contains double 'c' after the initial 'a' and double 'm' before the ending 'tion', making option B correct. Option A 'Accomodation' drops one 'c', a common misspelling, so it is incorrect.
