Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 21.963\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COCCCNC(=O)c1ccc(CS(=O)(=O)c2ccc(Br)cc2)o1
b: COc1ccc(NC(=O)c2nc(S(=O)(=O)Cc3cccc(C)c3)ncc2Cl)c(OC)c1
Answer: b. COc1ccc(NC(=O)c2nc(S(=O)(=O)Cc3cccc(C)c3)ncc2Cl)c(OC)c1
