Final answer:
The exact time to reset a touch faucet by disconnecting the battery is not specified without referring to the brand and model specific manual, but a common default period might be 15 minutes. Option B is correct.
Step-by-step explanation:
The question about resetting a touch faucet by disconnecting the battery does not relate to the provided options regarding urine output after drinking water. However, to answer the faucet question properly, one would typically refer to the user manual specific to the faucet brand and model.
Generally, the reset process may involve disconnecting the power source for a period of time. It's common for manufacturers to recommend anywhere from 5 minutes to 60 minutes as a reset period, but without the specific faucet instructions, it's not possible to provide an exact time.
In absence of a specific reference, option b. 15 minutes is often suggested as a standard reset time for electronic devices, though this is a generalized approach and not specific to touch faucets.
