Multiple Choice

Hold-up power is provided by five ____ volt 'C' cell batteries.

Explanation:
Hold-up power is the backup energy that keeps the radio running during a brief loss of main power. A C-cell battery normally provides about 1.5 volts. When you put five of these in series, their voltages add up to about 7.5 volts, which is the typical hold-up supply used in that setup. The other voltages don’t match the standard 1.5-volt C cells, and wouldn’t give the expected hold-up voltage.
