To determine the voltage drop across a battery, it depends on the context in which the battery is being used, including the circuit configuration and whether there are any resistive components present. Since the options you've provided are specific voltage values (-1.00 V, -3.00 V, -9.00 V, -12.00 V), it seems like this is related to a specific problem or context that isn't fully provided in your question.
If you have a circuit in mind (such as a series circuit with resistors, or a specific configuration), please elaborate on the circuit details, and I will be happy to help you calculate or identify the correct voltage drop across the battery.
