Task: Answer the multiple choice question.
Query: Which drug has a 2.936\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C1CCCN1c1ccc(Br)cc1
[b] O=C(Nc1ccc2c(c1)ncn2-c1ccccc1)c1ccco1
[c] CC(=NCc1cccnc1)C1=C(O)c2ccccc2C1=O
Answer: b. O=C(Nc1ccc2c(c1)ncn2-c1ccccc1)c1ccco1
