Task: Answer the multiple-choice question.
Query: Which drug exhibits a -4.136\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COc1ccc(/C=N\Nc2ccc([N+](=O)[O-])cc2[N+](=O)[O-])c(C(=O)O)c1OC
[b] O=C(NCc1ccc(F)cc1Cl)C1CCN(S(=O)(=O)N2CCCCC2)CC1
[c] O=Cc1cc(Br)c(OC(=O)N2CCOCC2)c(Br)c1
[d] COC(=O)c1ccc(NC(=O)CSc2nncn2-c2ccccn2)cc1
Answer: a. COc1ccc(/C=N\Nc2ccc([N+](=O)[O-])cc2[N+](=O)[O-])c(C(=O)O)c1OC
