First, we need to calculate the wattage that the circuit can handle: 
Watts = Voltage x Amperes 
Watts = 130 V x 20 A 
Watts = 2600 W

Then, we need to divide the total wattage by the wattage of each light bulb: 
150 W / bulb

2600 W / 150 W/bulb = 17.3 bulbs

Since we cannot have partial bulbs, we round down to get the final answer: 
Maximum number of 150 W light bulbs = 17.

Therefore, the best choice is C (17).
