If a carrier frequency has a second harmonic, what frequency is it?

Harmonics are integer multiples of a carrier frequency, and the second harmonic is twice the fundamental frequency. If the carrier is 4100 kHz, its second harmonic is 2 × 4100 = 8200 kHz. The other options represent the fundamental (4100 kHz), the third harmonic (3 × 4100 = 12300 kHz), and the fourth harmonic (4 × 4100 = 16400 kHz). So 8200 kHz is the second harmonic.
