Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.764\% 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)Nc1nnc(-c2c(-c3c(Cl)cccc3Cl)noc2C)o1
b: Fc1ccc(CNc2ncnc3c2cnn3-c2ccccc2)cc1
c: Cc1ccc(NS(=O)(=O)c2cccc(C(=O)O)c2)c(C)c1
Answer: b. Fc1ccc(CNc2ncnc3c2cnn3-c2ccccc2)cc1
