Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.418% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(N/N=C/c1c(Cl)[nH]c2ccccc12)c1ccc2c(c1)OCCO2
b: CC(=O)c1c(N2CCCC2)[nH]c(-c2ccccc2)nc1=S
Answer: b. CC(=O)c1c(N2CCCC2)[nH]c(-c2ccccc2)nc1=S
