Task: Answer the multiple-choice question.
Question: Which drug has a 4.268\% 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 additional words.
Options:
a) COc1ccc(OC)c(-c2cc(C3CCN(c4ncccc4[N+](=O)[O-])CC3)[nH]n2)c1
b) NC(=S)n1[nH]c(-c2ccccc2)c(N=Nc2ccccc2C(=O)N2CCOCC2)c1=O
c) Cc1ccc(C(=O)N/C(=C\c2ccc(F)cc2)C(=O)NCc2ccncc2)cc1
d) CCN(CC)C(=O)c1ccc(NC(=O)CSc2nnnn2-c2cc(OC)ccc2OC)cc1
e) Cc1ccc(N(CN2CCCC2=O)C(=O)c2ccc(C)c(C)c2)cc1
Answer: b. NC(=S)n1[nH]c(-c2ccccc2)c(N=Nc2ccccc2C(=O)N2CCOCC2)c1=O
