Task: Answer the multiple choice question.
Question: Which compound exhibits a 0.176\% 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=C(COC(=O)/C=C/c1ccc([N+](=O)[O-])cc1)NCc1ccco1
b) Cc1c(CCC(=O)O)c(=O)oc2cc3occ(-c4ccccc4)c3cc12
c) Cc1ccccc1C(=O)Nc1ccc2c(C#N)c3nc4ccccc4nc3n2c1
d) CCN(CC)S(=O)(=O)c1ccc(NC(=O)COC(=O)c2cnc(C)cn2)cc1
e) CC(=O)O/N=C(\N)c1cnn2c(C(F)(F)F)cc(C(F)(F)F)nc12
Answer: a. O=C(COC(=O)/C=C/c1ccc([N+](=O)[O-])cc1)NCc1ccco1
