English Grammar: Pronoun Usage in a Sentence

The correct answer is B. John, Mary and I.

Here's why:

• Pronoun Case: In this sentence, 'John, Mary and I' are the subjects of the verb 'had'. Subjects use the nominative case, which is 'I' in this instance.* Incorrect Options: * Options A and C use 'me', which is the objective case and incorrect for a subject position. * Option D places 'I' first, which while grammatically correct, is generally considered less formal in English.
