Task: Answer the multiple-choice question.
Question: Which compound has a -33.419\% human ether-à-go-go related gene (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.
Options:
a: O=C(C1CC(=O)N(c2ccc(Cl)cc2)C1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
b: COCCNc1nc2nonc2nc1NC(C)c1ccccc1Cl
c: COC(=O)c1ccc([C@H]2CC=CC(=O)O2)cc1
d: CCc1cccc(CC)c1NC(=O)COC(=O)/C(C#N)=C/c1ccc(OC)cc1
Answer: a. O=C(C1CC(=O)N(c2ccc(Cl)cc2)C1)N1CCN(Cc2ccc3c(c2)OCO3)CC1
