Task: Answer the multiple choice question.
Question: Which drug exhibits a 18.136% 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. COc1ccccc1C(=O)NC(=O)COC(=O)c1ccc([N+](=O)[O-])cc1Cl
b. CCOC(=O)c1ccc(NC(=O)Cn2c(C)nc3c(sc(=S)n3CC)c2=O)cc1
c. CCC1CCCCN1CCNS(=O)(=O)c1ccc2c(c1)oc(=O)n2C
Answer: a. COc1ccccc1C(=O)NC(=O)COC(=O)c1ccc([N+](=O)[O-])cc1Cl
