The Entropy Change of the Surroundings $\Delta$ S_surr, Is Related to Heat Transfer Q with Respect to to Heat

The entropy change of the surroundings, $\Delta$ S_surr, is related to heat transfer q with respect to the system and temperature T by

A) (-q/Tsys = $\Delta$ Ssurr .)
B) (+q/Tsys = $\Delta$ Ssurr .)
C) (-q/Tsurr = $\Delta$ Ssurr .)
D) (q/Tsurr = $\Delta$ Ssurr .)
E) none of these, unless the system undergoes a reversible process
