Task: Answer the MCQ question.
Question: Which compound exhibits a 9.898\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] COc1ccc(Cl)cc1NC(=O)c1nc2nc(C)cc(C(F)F)n2n1
[b] C[C@@H](NC(=O)[C@@H]1Cc2ccccc2CN1)C(=O)NC1CCCCC1
[c] O=C(O)CSc1nnc(COc2ccc([N+](=O)[O-])cc2)n1-c1ccccc1
[d] CCc1nc(C(N)=O)c2[nH]c(=O)n(-c3ccccc3F)c2n1
[e] COc1ccccc1/C=C1/C(=O)ON=C1C
Answer: e. COc1ccccc1/C=C1/C(=O)ON=C1C
