Problem statement: Answer the multiple choice question.
Question: Which drug has a 6.177\% 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] CC/C(=N/Nc1cccc(C)c1)c1cnnc(SC)n1
[b] COc1ccc(C(=O)/C(C)=N/O)cc1OC
[c] CC(C)/C=N/NC(=O)c1ccc(Cl)cc1
[d] O=C(N/N=C/c1cccc(Cl)c1Cl)Nc1ccccc1
Answer: c. CC(C)/C=N/NC(=O)c1ccc(Cl)cc1
