Answer 2

Given that Claudia wants to measure the brightness of the spotlight.

Mole is the SI unit of the amount of the substance and not the brightness of the light.

Candela is the SI unit of the brightness of the light.

Kelvin is the SI unit of the temperature.

And, the ampere is the SI unit of the current.

Thus to measure the luminosity or the brightness of the spotlight, Claudia should use the unit candela.

Thus the correct answer is option 2.
