Task: Answer the multiple choice question.
Question: Which drug has a -0.218% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COC(=O)CSc1nnc(-c2ccc(S(=O)(=O)N3CCCC3)cc2)n1C
b: CN(Cc1ccccc1)C(=O)c1nn2cccnc2c1Cl
c: O=C(NC(=S)Nc1ccccc1N1CCOCC1)c1sc2ccccc2c1Cl
d: CCOc1ccc(C2CC(c3cccc(Cl)c3)n3nc(N)nc3N2)cc1
Answer: b. CN(Cc1ccccc1)C(=O)c1nn2cccnc2c1Cl
