Solution

The correct option is B n2
Given,
Frequency of weakly damped harmonic oscillator =n1
Frequency of external periodic force =n2

Steady state is achieved when external force has acted for a sufficiently long time. Therefore, system starts oscillating with the frequency of driving force.
Frequency of oscillator will be equal to n2.
