Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.239\% 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.

b. CC(OC(=O)CNS(=O)(=O)/C=C/c1ccccc1)C(=O)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
c. CCCCn1c(N)c(N(CCC(C)C)C(=O)c2cc(CC)c(C)s2)c(=O)[nH]c1=O
d. CC(C)c1ccc(S(=O)(=O)Nc2ccc(O)c(Sc3ncn[nH]3)c2)cc1
Answer: b. CC(OC(=O)CNS(=O)(=O)/C=C/c1ccccc1)C(=O)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
