Task: Answer the multiple choice question.
Query: Which compound has a 3.912\% 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 other words.
Options:
a.) COc1ccccc1C1CC(=O)NC(C)=C1C(=O)OC(C)C
b.) O=[N+]([O-])c1cccnc1N1CCC(c2cc(-c3ccc(Cl)cc3Cl)n[nH]2)CC1
c.) Nc1ccc(C23CC4CC(CC(O)(C4)C2)C3)cc1
d.) CCn1c(SCC(=O)n2c(C)c(C)c3ccccc32)nnc1-c1ccco1
e.) O=C(/C(=C/O)N=Nc1ccccc1Cl)c1ccccc1
Answer: a. COc1ccccc1C1CC(=O)NC(C)=C1C(=O)OC(C)C
