We know that entropy of gas is highest then liquid then solid....in option A there is only solid so we can cancel it...in option B there is also no gaseous state in product...in option c there gas is turning into solid so decrease in entropy....in option d from 2 gaseous molecule we got 2 molecule .....so no entropy change.....in option a solid turns to has so correct answer is option e
