If the internal energy (U) of a system is dependent on the pressure (p) and volume (V) of the system, then, according to the cyclic rule \(\left(\frac{\partial U}{\partial p}\right)_V\left(\frac{\partial p}{\partial V}\right)_U\left(\frac{\partial V}{\partial U}\right)_p\)

is equal to

1. (a) zero
2. (b) +1
3. (c) −1
