Problem statement: Answer the multiple-choice question.
Query: Which drug has a 15.986\% 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, c, or d without using any additional words.
Options:
a: COc1ccc(-n2c3c(c(=O)[nH]c2=O)C(NC(C)=O)(C(F)(F)F)C(=O)N3)cc1
b: COc1cc(C(=O)Nc2nccs2)c(Br)c(OC)c1OC
c: Clc1cc2cccnc2c2ncccc12
d: O=S(=O)(c1ccc(F)c(Cl)c1)N1CCCC1
Answer: b. COc1cc(C(=O)Nc2nccs2)c(Br)c(OC)c1OC
