Task: Answer the multiple-choice question.
Question: Which drug exhibits a -3.474\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=C(Nc1ccc2c(c1)Cc1ccccc1-2)c1cccnc1
[b] O=c1c(Cl)c(NCc2ccco2)cnn1C12CC3CC(CC(C3)C1)C2
[c] COc1ccc(N2CCN(S(=O)(=O)c3ccc(C(=O)NC4CCCC4)cc3)CC2)cc1
Answer: a. O=C(Nc1ccc2c(c1)Cc1ccccc1-2)c1cccnc1
