Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a -8.234\% 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(-c2cnccn2)n1Cc1ccco1)c1ccc(Cl)cc1
b: CCOc1ccc(NC(=O)/C(C#N)=C/c2ccc(N3CCCC3)c(C)c2)cc1
Answer: a. O=C(CSc1nnc(-c2cnccn2)n1Cc1ccco1)c1ccc(Cl)cc1
