Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 0.146\% 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 additional words.
Options:
a: COc1ccc2cc(C#N)c(SCC(=O)N3CCCC3)nc2c1
b: Oc1ccc(C=NC2CCCCC2)cc1
Answer: a. COc1ccc2cc(C#N)c(SCC(=O)N3CCCC3)nc2c1
