Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a -17.173\% 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, or d without using any other words.
Options:
a. COc1cc(N/C(N)=N/c2nc(C)cc(C)n2)c(OC)cc1Cl
b. CNC(=O)c1nc(C)c(C2(C)CC(c3cccc([N+](=O)[O-])c3)=NO2)s1
c. CCOC(=O)CSc1cc(C)c(C#N)c2nc3ccccc3n12
d. CCCC1=Nc2cc(C(=O)N3CCN(c4ccccn4)CC3)ccc2Sc2ccc(C)cc21
Answer: a. COc1cc(N/C(N)=N/c2nc(C)cc(C)n2)c(OC)cc1Cl
