Task: Answer the multiple-choice question.
Query: Which drug has a 13.806\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COC(=O)c1nccnc1C(=O)Nc1ccccc1N1CCOCC1
b: CC1Nc2ncnc(N3CCc4ccccc4C3)c2N(Cc2ccc(Br)cc2)C1=O.O=C(O)C(F)(F)F
c: COCCCn1c(-c2ccc(Cl)cc2)n[nH]c1=S
d: CCC1CCCCN1S(=O)(=O)c1ccc(NC(=O)C2CCCO2)cc1
e: CN1CC(C(=O)c2cccs2)C(c2ccc(Cl)cc2)C1
Answer: b. CC1Nc2ncnc(N3CCc4ccccc4C3)c2N(Cc2ccc(Br)cc2)C1=O.O=C(O)C(F)(F)F
