Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.286\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=S(=O)(Nn1cnnc1)c1ccccc1
b: Cc1cccc(C)c1N(CC(=O)N1CCN(C)CC1)S(C)(=O)=O
c: CCOC(=O)N1CCN(CC(O)COCc2cc(OC)c(OC)c(OC)c2)CC1.Cl
Answer: c. CCOC(=O)N1CCN(CC(O)COCc2cc(OC)c(OC)c(OC)c2)CC1.Cl
