We can use the formula:
Vs/Vp = Ns/Np
where Vs is the secondary voltage (6V), Vp is the primary voltage (120V), Ns is the number of turns in the secondary, and Np is the number of turns in the primary. Solving for Ns, we get:

Ns = (Vs/Vp) x Np
Ns = (6/120) x 500
Ns = 25

Therefore, the number of turns in the secondary is 25, which corresponds to choice B.
