Task: Answer the multiple choice question.
Question: Which compound has a 12.779\% human ether-à-go-go related gene (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=C(NO)c1ccccc1O
[b] FC(F)(F)c1cccc(NC(=S)N2CCCCCC2)c1
[c] C/C(=N\Nc1ccc([N+](=O)[O-])cc1[N+](=O)[O-])C(C)C(C)C
[d] C=CC(O)(C#CCN(CC)CC)c1ccccc1
[e] O=C(O)c1cc(Oc2ccc(C(F)(F)F)cc2Cl)ccc1[N+](=O)[O-]
Answer: a. O=C(NO)c1ccccc1O
