Task: Answer the multiple-choice question.
Query: Which drug exhibits a 1.993% human ether-à-go-go related gene (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 additional words.
Options:
a) CC1CN(CC(=O)Nc2cccc(C(=O)Nc3cccc(C(F)(F)F)c3)c2)CC(C)O1
b) CCOc1c2ccccc2nn1CCO
c) CCn1c(=O)c(C(=O)Nc2ccccn2)c(O)c2ccccc21
d) COc1cc(NC(=O)C2CCCN2C(=O)C2CCC(C)CC2)cc(OC)c1OC
e) O=C(Nc1ccc([N+](=O)[O-])cc1)c1cccc(S(=O)(=O)Nc2ccccn2)c1
Answer: e. O=C(Nc1ccc([N+](=O)[O-])cc1)c1cccc(S(=O)(=O)Nc2ccccn2)c1
