Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 10.158\% 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: CC(Oc1cccc(Cl)c1)C(=O)N1CCN(c2ncccn2)CC1
b: COc1ccc(-c2c3c(cc(C)[n+]2[O-])oc2ccc(OC)cc23)cc1
c: Cc1c(-c2ccc(F)cc2)[n+](=O)c(-c2ccc(F)cc2)c(C)n1[O-]
Answer: c. Cc1c(-c2ccc(F)cc2)[n+](=O)c(-c2ccc(F)cc2)c(C)n1[O-]
