We can use the formula Vp/Np = Vs/Ns (where Vp and Np are the voltage and turns on the primary, and Vs and Ns are the voltage and turns on the secondary) to solve for Ns.

Vp = 120 V (from the outlet)
Np = 500 turns (given)
Vs = 6 V (required for the game)
Ns = ?

Plugging in the values, we get:

120 V / 500 turns = 6 V / Ns

Solving for Ns:

Ns = (6 V x 500 turns) / 120 V
Ns = 25 turns

Therefore, the secondary needs to have 25 turns. Choice B is the correct answer.
