Task: Answer the multiple choice question.
Query: Which drug has a 11.899\% 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 additional words.
Options:
a: O=C(O)C1CCCN1C(=O)C12CC3CC(CC(C3)C1)C2
b: COc1cccc(CN2CCc3[nH]c(=S)[nH]c(=O)c3C2)c1
c: O=C(C1=C[C@H](C2CC2)C[C@H](OCCCCO)O1)N1CCN(Cc2ccccc2)CC1
d: C/C(Cc1ccccc1)=N\NC(=O)CNC(=O)c1ccccc1F
Answer: a. O=C(O)C1CCCN1C(=O)C12CC3CC(CC(C3)C1)C2
