Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.886\% hERG inhibition at 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=C1NC(c2ccc(Cl)c([N+](=O)[O-])c2)Nc2ccccc21
b) CC(Sc1nc2ccccc2c(=O)n1C)C(=O)NC1CCCCC1C
c) Cc1ccccc1OCC(=O)OC(C)CN1CCN(C)CC1.Cl
d) CC(Oc1ccc(C#N)cc1)C(=O)c1ccc(F)c(F)c1
e) Cl.Clc1ccc(CNC2CN3CCC2CC3)cc1
Answer: a. O=C1NC(c2ccc(Cl)c([N+](=O)[O-])c2)Nc2ccccc21
