Task: Answer the multiple choice question.
Question: Which compound has a 9.100% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCc1c(-c2ccccc2)[n+](=O)c2c(n1[O-])CCC2
b. CCOc1ccc(NC(=O)C(=O)NCCN2CCN(S(=O)(=O)c3ccc(C)cc3)CC2)cc1
c. COCCNC(=O)c1cc(S(=O)(=O)N(C)c2ccccc2OC)ccc1C
Answer: a. CCc1c(-c2ccccc2)[n+](=O)c2c(n1[O-])CCC2
