Task: Answer the multiple choice question.
Query: Which compound exhibits a 16.106\% 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) O=C1c2ccccc2C(=O)N1CCc1ccccn1
b) O=C1Nc2c(c(=O)[nH]c(=O)n2Cc2ccccc2)C1(NS(=O)(=O)c1ccccc1)C(F)(F)F
c) COc1ccc(CC(=O)NNS(=O)(=O)c2ccccc2)cc1OC
d) O=C(CNS(=O)(=O)c1ccc([N+](=O)[O-])cc1)N/N=C\c1ccc(O)cc1
e) O=C(NCCc1ccc(F)cc1)C(=O)Nc1cc2c3c(c1)CC(=O)N3CCC2
Answer: a. O=C1c2ccccc2C(=O)N1CCc1ccccn1
