Answer:
B. to
It never occurred <u>to</u> me to ask him for proof of identity.
Explanation:
<em>To occur to</em> (someone) is a phrasal verb that means <em>to come into someone's mind</em>.
Phrasal verbs are verbs that consist of the main verb and an adverb or a preposition, or both. Usually, we can't determine their meaning just based on what these words mean individually. For example, the verb <em>to occur</em> means <em>to happen</em>, while<em> to </em>has many meanings and can function as a preposition, adverb, and the infinitive marker. This knowledge doesn't help us determine what the phrasal verb <em>to occur to</em> means, though.
