Task: Answer the multiple choice question.
Query: Which compound exhibits a 20.992\% 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(=O)N1CCN(C(=S)NC(=O)c2c(-c3ccccc3Cl)noc2C)CC1
b: O=C(O)c1cccc(NS(=O)(=O)c2ccc(Cl)c(C(=O)O)c2)c1
c: CC(=O)NC1(C(Cl)(Cl)Cl)Oc2ccccc2O1
Answer: b. O=C(O)c1cccc(NS(=O)(=O)c2ccc(Cl)c(C(=O)O)c2)c1
