Task: Answer the multiple-choice question.
Query: Which drug exhibits a 6.681\% 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 additional words.
Options:
a: O=c1[nH]c(C2CCN(S(=O)(=O)c3ccccc3)CC2)nc2c1nnn2Cc1cccc(Cl)c1
b: O=C(Nc1ccc2c(c1)OCO2)C1CC(=O)N(c2cccc(Cl)c2)C1
c: O=C(O)CCSc1nnc(-c2ccncc2)n1-c1ccccc1
d: CC1(C)Cc2nc3[nH]c(=S)[nH]c(=O)c3cc2CO1
Answer: b. O=C(Nc1ccc2c(c1)OCO2)C1CC(=O)N(c2cccc(Cl)c2)C1
