Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.513\% 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: Cc1nc2cc(Nc3nnc(-c4ccccc4)c4ccccc34)ccc2n1C
b: O=c1cc(O)c2ccccc2n1Cc1ccccc1F
c: Cn1c(=O)oc2cc(S(=O)(=O)NCCN3CCCCCC3)ccc21
d: COc1ccc(Cl)cc1C(=O)NCc1cnn(C)c1C
Answer: b. O=c1cc(O)c2ccccc2n1Cc1ccccc1F
