Firstly voltage follower non inverting se banta hai. And secndly there will be no feedback resistance. So answer will b false.

I think Answer is false. Voltage follower needs input to be given in non inverting terminal and the feedback is given to inverting terminal. For unity gain.

R1 = large as possible & Rf = small as possible then vo= (1+Rf/Ri)Vin then Vo=Vin so that circuit works as the voltage follower.
