Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 11.527\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(NC(=S)NC(CO)Cc1ccccc1)c1ccc(F)cc1
b N#C/C(=C\Nc1ccc(Oc2ncc(C(F)(F)F)cc2Cl)cc1)C(=O)CCl
c CCN(Cc1ccccc1)S(=O)(=O)c1cn(C)cn1
d O=C(Cc1cccs1)NC(c1ccccc1)c1ccccc1
Answer: c. CCN(Cc1ccccc1)S(=O)(=O)c1cn(C)cn1
