Task: Answer the MCQ question.
Question: Which drug has a 15.882\% 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: Cc1cc(C)c(S(=O)(=O)c2ccc(Cl)cc2)c(Cl)n1
b: Nc1c(-c2ccccc2)c(CSc2nc3ccccc3[nH]2)nn1-c1ccc(Cl)cc1
c: C/C(=N\N=C(N)N)c1ccc(Cl)c(Cl)c1.CC(=O)O
d: CC(=O)Nc1cccc(Oc2cc(C#N)c(C#N)cc2N2CCCCCC2)c1
e: C/C(CCCO)=N/Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
Answer: b. Nc1c(-c2ccccc2)c(CSc2nc3ccccc3[nH]2)nn1-c1ccc(Cl)cc1
