Problem statement: Answer the multiple-choice question.
Query: Which drug has a 1.946\% 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 O=C(N[C@@H](Cc1c[nH]c2ccccc12)C(=O)O)c1ccccc1Cl
b CCCCN(C(=O)c1cccc(-n2cnnn2)c1)c1c(N)n(CC(C)C)c(=O)[nH]c1=O
Answer: a. O=C(N[C@@H](Cc1c[nH]c2ccccc12)C(=O)O)c1ccccc1Cl
