Task: Answer the multiple choice question.
Query: Which compound exhibits a 13.449\% 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] CCOC(=O)c1c(NC(=O)CCC(=O)O)sc2c1CC(C)(C)OC2
[b] O=C(O)CC1C(=O)NCCN1C/C=C/c1ccccc1
[c] CCOC(=O)c1c(S(=O)(=O)NCC(=O)Nc2ccccc2)c(C)n(C)c1C
Answer: a. CCOC(=O)c1c(NC(=O)CCC(=O)O)sc2c1CC(C)(C)OC2
