Task: Answer the multiple choice question.
Query: Which drug exhibits a -4.238\% 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: Cc1cccn2c(=O)c3cc(C#N)c(=NC(=O)c4cccs4)n(CC(C)C)c3nc12
b: CC(=O)c1ccc2c(c1)C1C=CCC1C(c1ccncc1)N2
Answer: b. CC(=O)c1ccc2c(c1)C1C=CCC1C(c1ccncc1)N2
