Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.766\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. COc1ccc(CCN(C)C2CCCN(S(C)(=O)=O)C2)cc1OC
b. COC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCN(C)C)C2c2ccccc2OC)c1C
c. COc1cccc(/C=C2\SC(=O)N(CCC(=O)NCCCn3ccnc3)C2=O)c1
d. O=C(Nc1ccc(Nc2ccccc2)cc1)c1cc([N+](=O)[O-])ccc1Cl
Answer: b. COC(=O)c1[nH]c(C)c(/C(O)=C2\C(=O)C(=O)N(CCN(C)C)C2c2ccccc2OC)c1C
