Task: Answer the multiple-choice question.
Question: Which compound exhibits a -54.370% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. COc1ccc(NC(=O)C/C(C)=N/NC(=O)c2cccs2)c([N+](=O)[O-])c1
b. Cc1cc(C)n(-c2ccc(C(=O)OCC(=O)NCc3ccc(F)cc3)cc2)n1
c. COc1ccc(-c2noc(CN(C)C(=O)c3ccc4c(c3)OCO4)n2)cc1OC
d. CCn1ncc(Br)c1C(=O)Nc1cc([N+](=O)[O-])ccc1C
Answer: a. COc1ccc(NC(=O)C/C(C)=N/NC(=O)c2cccs2)c([N+](=O)[O-])c1
