Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 0.060\% 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: O=C(CSc1nnc(-c2ccccn2)o1)Nc1ccccc1
b: CCC(C)NS(=O)(=O)c1ccc(OCC(=O)NCc2ccc3c(c2)OCO3)cc1
Answer: a. O=C(CSc1nnc(-c2ccccn2)o1)Nc1ccccc1
