The voltage of the car battery can be calculated using Ohm's Law, which states that V = IR, where V is the voltage, I is the current, and R is the resistance.
Plugging in the values given:
V = 0.87 amperes * 15 ohms
V = 13.05 volts
Therefore, the voltage of the car battery is approximately 13 volts, so the answer is option b.
