Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.417\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCOC(=O)C1CCCN(C(=O)/C=C/c2cc(OC)c(OC)c(OC)c2)C1
b: COc1ccccc1NC(=O)C1=C(C)NC2=C(C(=O)CCC2)C1c1ccc2c(c1)OCO2
c: O=C(CCc1nnc2ccc(NCc3ccco3)nn12)Nc1cc(F)ccc1F
d: O=C(CC1CCCCC1)NCc1ccc(Cl)cc1
Answer: a. CCOC(=O)C1CCCN(C(=O)/C=C/c2cc(OC)c(OC)c(OC)c2)C1
