Task: Answer the multiple choice question.
Question: Which drug has a -3.549\% 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: O=C(Nc1cc([N+](=O)[O-])ccc1Cl)c1ccc2c(c1)OCO2
b: CSc1nc(N)c2c3c(sc2n1)COC(C(C)C)C3
c: CCOc1ccc(/C=C/C(=O)N(CC)CC(=O)Nc2ccc3c(c2)OCCO3)cc1OC
d: NC(=O)Cc1nc(-c2ccc(F)cc2)cs1
Answer: b. CSc1nc(N)c2c3c(sc2n1)COC(C(C)C)C3
