Option (d)

Explanation:

The first law of thermodynamics can be captured in the following equation, which states that the energy of the universe is constant. Energy can be transferred from the system to its surroundings, or vice versa, but it can't be created or destroyed

DeltaE_"Universe"=DeltaE_"Sys"+DeltaE_"Sur"=0

Another form of equation that expresses this law is

DeltaE_"Sys"=q+w" (sign convention IUPAC)"

( Hera Deltaq and Delta w are not allowed and Delta E is a must)

So Option (d) is acceptable
