Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 4.358\% 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.) O=C(Nc1ccccc1)N1CCSc2cc(Cl)ccc21
b.) COC(=O)c1c(C)[nH]c(C(=O)NCc2ccco2)c1C
c.) O=C(NCc1ccco1)C1CCN(S(=O)(=O)c2cccc([N+](=O)[O-])c2)CC1
d.) O=C(NC(=S)NCCc1ccccc1)c1ccccc1F
e.) COC1=CCC2([N+](=O)[O-])CN(CC(=O)O)CC1([N+](=O)[O-])C2
Answer: b. COC(=O)c1c(C)[nH]c(C(=O)NCc2ccco2)c1C
