Task: Answer the multiple-choice question.
Query: Which drug has a -19.794\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) O=C(O)c1ccc(S(=O)(=O)Cc2ccccc2)cc1
b.) O=C(NCc1cccnc1)c1cc2nc(-c3cccs3)cc(C(F)(F)Cl)n2n1
c.) Cn1c(=O)c2c(nc(CN3CCN(C(=O)c4ccco4)CC3)n2Cc2ccccc2)n(C)c1=O
d.) Cc1ccccc1N1CC(c2nc3ccccc3[nH]2)CC1=O
e.) Cc1ccc(Nc2nnc(SCc3cc(=O)n4ccsc4n3)s2)c(C)c1
Answer: b. O=C(NCc1cccnc1)c1cc2nc(-c3cccs3)cc(C(F)(F)Cl)n2n1
