Task: Answer the multiple choice question.
Question: Which drug has a -2.341\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(COC(=O)c1ccco1)NCCc1ccc(Cl)cc1
b: COC(=O)c1ccc(N2C(=O)CC(N3CCN(c4ccccc4)CC3)C2=O)cc1
c: CCCCC(=O)N/N=C/c1c(O)n(CCc2ccc(OC)c(OC)c2)c(=O)[nH]c1=O
Answer: a. O=C(COC(=O)c1ccco1)NCCc1ccc(Cl)cc1
