A. An exothermic reaction that increases in entropy
B. An endothermic reaction that decreases in entropy

D. An exothermic reaction that decreases in entropy

Isn't that A?
dG = dH - TdS.
If dH is - and dS is +, then -TdS will be negative; thus dG will ALWAYS be negative.

it's actually endothermic reaction that decreases in entropy.
