Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -0.657\% 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) COc1ccc2c(ccc[n+]2CC(=O)c2ccccc2)c1.[Br-]
(b) O=P(NS(=O)(=O)c1ccccc1)(Oc1ccccc1)Oc1ccccc1
Answer: b. O=P(NS(=O)(=O)c1ccccc1)(Oc1ccccc1)Oc1ccccc1
