Which of the following systems shows an increase in entropy?

spilling a jar of pennies
steam condensing to liquid water
would it be C?
Making a heat engine that uses its exhaust heat to do work is restricted according to which principle?
second law of thermodynamics
conservation of matter
first law of thermodynamics
conservation of energy
would it be A?
Increase entropy is an increase in disorder,,,, I think the penny jar is the answer.
Not sure I know the answer to the second one....if I were taking a test, I would guess First Law ....but that would be a guess. Sorry
