Solution

The phase shift provided by the feedback network in a Wein Bridge Oscillator based on op-amp tuned at 1KHz is 0. So, the correct answer is b.0.

Here's why:

A Wein Bridge Oscillator is a type of oscillator which uses a frequency selective bridge (Wein Bridge) in its feedback network. The bridge is balanced when the phase shift through the bridge is zero, which is the condition for oscillation. Therefore, regardless of the frequency at which the oscillator is tuned, the phase shift provided by the feedback network is always zero.
