Task: Answer the multiple choice question.
Query: Which drug has a 13.098\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) C/C(=N/N=C/c1ccccc1O)c1ccccc1O
b) CN(CC(=O)Nc1ccccc1F)CC(=O)Nc1ccccc1Br
c) O=C(CCSCc1ccccc1F)N1CCN(c2ccccn2)CC1
d) NC(=O)N/N=C/c1cn(-c2ccccc2)nc1-c1cccnc1
Answer: b. CN(CC(=O)Nc1ccccc1F)CC(=O)Nc1ccccc1Br
