Task: Answer the multiple choice question.
Query: Which drug has a -18.928\% 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: COc1cc2[nH]c3c(N4CCN(c5ccccn5)CC4)ncnc3c2cc1OC
b: O=C(Nc1ccc(SC(F)F)cc1)C1CC(=O)N(Cc2ccccc2)C1
Answer: b. O=C(Nc1ccc(SC(F)F)cc1)C1CC(=O)N(Cc2ccccc2)C1
