For whom did Shelia make these cookies.

In formal English, the object pronoun 'whom' is used after the preposition ('for' in the test sentence). In informal, natural English, you would say: Who did Shelia make these cookies for?

In questions, 'whom' means 'which person/s'. In statements, it means 'the person/s that': The man whom I like is sitting over there; the people with whom he came have now left. Informal English: The man (that) I like is sitting over there; the people (that) he came with have now left.
