Explanation:

A single - bit can represent two states. Options D (source of power: battery/adapter) and E (bluetooth status: disconnected/connected) have two distinct states each. The other options (time of day, wireless connectivity level, day of the week, battery charge level) have more than two possible values and thus require more than one bit to represent.

Answer:

D. The source of power (battery/adapter)
E. The bluetooth status (disconnected/connected)
