Task: Answer the multiple-choice question.
Question: Which compound exhibits a -3.311\% 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, or c without using any other words.
Options:
(a) CN=C1S/C(=C\c2cc(C)n(-c3ccccc3F)c2C)C(=O)N1C
(b) O=C(CSc1nc2ccccc2c(=O)n1-c1ccc(Cl)cc1)N/N=C/C=C/c1ccccc1[N+](=O)[O-]
(c) CCOC(=O)c1c(N2C(=O)CC(Sc3ccccc3C(=O)O)C2=O)sc2c1CCCC2
Answer: b. O=C(CSc1nc2ccccc2c(=O)n1-c1ccc(Cl)cc1)N/N=C/C=C/c1ccccc1[N+](=O)[O-]
