Answer:

D) All of the above

Explanation:

To understand why we need to study case by case:

A) RF is shorted by a solder bridge: If RF is shorted, the output is going to be at the same potential that the inverting input due to a virtual short circuit (the inverting input is 0V because the non-inverting input is GND)

B) R1 is open: If R1 is open there is not input voltage to amplify therefore the output is 0V

C) Vi = 0: If Vi is equal zero there is not input voltage to amplify therefore the output is 0V

Note: Because there's is not schematic we assume the one in the picture down below, our logical explanation is complemented with a simulation that matches our results. For our case the amplifier requires a positive and negative supply, so we use an inverting amplifier with +11 V and -11V power supply.
