What is the power delivered by the battery in this circuit

As in the circuit sketched below, 8.00 ! and 2.00 ! resistors are connected to a
6.00 volt battery.
What is the power delivered by the battery in this circuit?
a. one-half watt or less
b. 0.600 W
c. 3.60 W
d. ten watts or more
e. none of these

Since two resistors are connected so that the resultant resistance is 8+2=10ohms
Battery voltage V=6volts
Therefore power extracted from the battery P=V^2/R=36/10=3.6W. So answer is c.
