Problem statement: Answer the multiple-choice question.
Question: Which drug has a -6.219\% 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 or b without using any other words.
Options:
a.) COC(=O)CSc1nc(C)c(C(C)=O)cc1C#N
b.) COc1ccc(Cc2nnc(NC(=O)c3ccc(Cl)c([N+](=O)[O-])c3)s2)cc1
Answer: a. COC(=O)CSc1nc(C)c(C(C)=O)cc1C#N
