Task: Answer the multiple choice question.
Query: Which drug has a 5.907% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCOc1ccccc1/C=C\c1nc(O)c([N+](=O)[O-])c(=O)[nH]1
b O=C(NNC(=S)Nc1ccc(Cl)c(Cl)c1)c1ccccn1
c c1ccc2c(c1)[nH]c1ccccc12
d COc1ccc2c(c1)N(C)/C(=C1/SC(=S)N(NC(C)=O)C1=O)S2
e C=CCN1CCC2(C)c3cc(O)ccc3CC1C2C.Cl
Answer: a. CCOc1ccccc1/C=C\c1nc(O)c([N+](=O)[O-])c(=O)[nH]1
