What does he want to do with his money from the bank account?

The choice indicating that he wants to "withdraw" money from the bank account is appropriate because it conveys the action of taking money out of the account. This is a common banking term that specifically refers to accessing funds that are held in a financial institution.

Withdrawing money suggests that he intends to utilize the funds for some purpose outside the bank, whether for spending or using in a different context. This contrasts with other options, which imply actions that either keep the money within the bank (like depositing or saving) or placing it into a different financial avenue (like investing). Therefore, if the intent is to access available cash, "withdraw" is the most fitting choice.
