Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.328\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) COc1ccc(-c2nc(CN3CCC(C(=O)NC4CCCC4)CC3)c(C)o2)cc1OC
b) O=C(O)Cc1c(-c2ccccc2Cl)c2cc(Br)ccc2[nH]c1=O
c) CNC(=O)Nc1cc(C(F)(F)F)cc(C(F)(F)F)c1
Answer: b. O=C(O)Cc1c(-c2ccccc2Cl)c2cc(Br)ccc2[nH]c1=O
