b. manual valve.

c. solenoid valve.

d. motor- driven pump.

a wet-carpet cleaner that carries it's own water supply has water pressure created by

D. motor- driven pump.

Explanation:

Faucet mixing valves can mix different sources of water current, but they need constant pressure provided by a pipe system.

Manual valves are the same as the first one, they required a pipe with pressure.

The solenoid valve like the first three options requires that the pipe provides the pressure it requires to free the water.

However, the motor-driven pump doesn't require a pipe with pressure because it can create pressure with the motor. So this is our correct answer.
