A) equal to
In a closed system, the total energy prior to an energy transformation is equal to the total energy after.
A closed system is defined as an isolated region surrounded by a boundary across which no transfer of matter or energy can take place.
Hence, even if there is an energy transformation in a closed system, the overall energy of the closed system remains constant.
Energy cannot be created nor destroyed. It can only be changed from one form to another. So when an energy transformation takes place in a closed system, the total amount of energy before the transformation is always equal to the total amount of energy after. A
Based on my information to this, I believe sense (it would be a closed system), this would most likely be considered to be (equal to) the total energy after.
But, if it was not a (closed system), it would not be unrelated because the energetic system would not be that greatly increased.
So, it really depends whether the system closes up, or whether it would be free of energy.
So, in this case, your correct option to this answer would be (option A).
In a closed system, the total energy prior to an energy transformation is unrelated to the total energy after.
I hope this helps you!
