Task: Answer the multiple choice question.
Query: Which compound has a 9.281\% 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 additional words.
Options:
[a] Br.CCn1c(=N)n(CC(=O)c2ccco2)c2ccccc21
[b] COc1cc(/C=C/C(=O)O)cc(S(=O)(=O)Nc2ccccc2SC)c1OC
[c] CC(=O)COc1cc2c(-c3cc4ccccc4o3)cc(=O)oc2cc1C
Answer: a. Br.CCn1c(=N)n(CC(=O)c2ccco2)c2ccccc21
