B Correct answer
Explanation

Damping slightly reduces the oscillation frequency because the damping force opposes motion, effectively making each cycle take marginally longer. The damped frequency is given by ωd = ω₀√(1 - ζ²) where ω₀ is the undamped frequency and ζ is the damping ratio, making ωd < ω₀ for any damping present.
