Task: Answer the multiple-choice question.
Query: Which drug has a 5.595\% 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) Cc1c(NC(=S)NC(=O)c2ccccc2)c(=O)n(-c2ccccc2)n1C
(b) O=C(CNc1ccc2ccccc2c1)N/N=C/c1ccc([N+](=O)[O-])o1
Answer: b. O=C(CNc1ccc2ccccc2c1)N/N=C/c1ccc([N+](=O)[O-])o1
