Problem statement: Answer the multiple choice question.
Question: Which compound has a 12.012\% 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, d, or e without using any additional words.
Options:
[a] CCOC(=O)c1cc(NC(=O)c2cccnc2)cc(C(=O)OCC)c1
[b] COc1ccc(Nc2nc(C(=O)N(CCO)Cc3ccccc3)cs2)cc1
[c] CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2c1cccs1
[d] CC(NS(=O)(=O)OCC(Cl)(Cl)Cl)c1ccc(Br)cc1
[e] CCCc1nnc(SCC(=O)Nc2ccc(OCC)cc2)n1N
Answer: c. CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C2c1cccs1
