Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.008\% 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: Cc1ccc(/C=N/NC(=O)c2ccccc2OCc2cccc(Br)c2)o1
b: NS(=O)(=O)c1ccc(NC(=O)COc2ccc(C(=O)c3ccc(F)cc3)cc2)cc1
c: Cc1ccc(S(=O)(=O)C(C#N)c2nc3ccccc3nc2N2CCN(C)CC2)cc1
d: O=C1CC2(CCCCCC2)Oc2ccc(Cl)cc21
Answer: d. O=C1CC2(CCCCCC2)Oc2ccc(Cl)cc21
