Task: Answer the multiple-choice question.
Question: Which compound has a 15.691\% 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(Cn1nnc(-c2ccccc2NC(=O)c2ccco2)n1)Nc1ccccc1
b: O=C(c1ccc([N+](=O)[O-])cc1[N+](=O)[O-])n1cnc2ccccc21
c: O=C(CSc1cccc[n+]1[O-])Nc1ccc2c(c1)OCCO2
d: O=C(O)CC1C(=O)NCCN1C/C=C/c1ccccc1
Answer: a. O=C(Cn1nnc(-c2ccccc2NC(=O)c2ccco2)n1)Nc1ccccc1
