Final answer:
Abigail blames Tituba when questioned by Reverend Hale and claims to have seen her with the devil, which corresponds to answer choice A.
Step-by-step explanation:
The answer to the question of who Abigail blames when questioned by Reverend Hale in Act I of ‘The Crucible’ is Tituba, and the proof she offers is her claim to have seen Tituba with the devil. Therefore, the correct answer is A) She blames Tituba and claims to have seen her with the devil. It's important to note that Abigail accuses Elizabeth Proctor later in the play, but not at this point in Act I. The poppet as evidence comes into play later, specifically in Act II.
