To solve the problem it is necessary to refer to the definition of entropy.

Entropy is defined aso

[tex]\Delta S = \frac{\Delta Q}{T}[/tex]

Where,

[tex]\Delta Q =[/tex] Heat exchange

T = Temperature

Since the heat exchange is conserved and it is an isothermal process where the temperature remains constant the change in entropy remains the same, ie [tex]\Delta S = 0[/tex] (Reamins same)

Therefore the correct answer is C.
