Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.611\% human ether-à-go-go related gene (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 other words.
Options:
a) C=C[C@@H]1c2cc(C)ccc2N(S(=O)(=O)c2ccc(C)cc2)[C@H](c2ccc(OC(C)=O)cc2)C1(C#N)C#N
b) CN(CC(=O)Nc1ccc(F)cc1)C(=O)c1cccc(NS(=O)(=O)c2ccccc2)c1
c) O=C(NC1CC1)C1CCN(S(=O)(=O)c2cc(Cl)ccc2Cl)CC1
d) CCn1nc([N+](=O)[O-])c(C(C#N)c2nc3ccccc3s2)c(Cl)c1=O
e) O=C(c1ccccc1F)N1CCc2ccccc21
Answer: d. CCn1nc([N+](=O)[O-])c(C(C#N)c2nc3ccccc3s2)c(Cl)c1=O
