Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 18.377\% 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 other words.
Options:
a) CCCCCc1nnc(NS(C)(=O)=O)s1
b) O=c1cc(-c2ccccc2Cl)oc2c(NS(=O)(=O)c3cc(Cl)cc(Cl)c3O)ccc(O)c12
Answer: b. O=c1cc(-c2ccccc2Cl)oc2c(NS(=O)(=O)c3cc(Cl)cc(Cl)c3O)ccc(O)c12
