A)This cannot be answered with the information given.
B)The power decreases to 2/3 of the original amount.
C)The power increases to 1.5 times the original amount.
D)The power increases to 6 times the original amount.

The power delivered to a resistor is given by $P = IV$, where $I$ is the current and $V$ is the voltage. If the voltage is doubled and the current triples, the new power is $P_{new} = 3I \times 2V = 6IV$, which is 6 times the original power.
