The best form to complete the sentence in option A is "will". The sentence should read: "What time will your sister arrive?" This is because "will" is used to talk about future events that are planned or scheduled. In this case, the speaker is asking about the time their sister will arrive, which is a future event. The other options, "will be going to" and "shall", are not appropriate in this context. "Will be going to" is used to talk about future plans or intentions, but it is not the correct form to use when asking about a specific time. "Shall" is used to make suggestions or offers, and it is not the correct form to use when asking about a future event. Therefore, the correct answer is "will".
