Problem statement: Answer the multiple choice question.
Query: Which drug has a 19.566\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1ccccc1CN1CCC(CNS(=O)(=O)c2cc(-c3cc(C)no3)ccc2OC)CC1
b: CC(=N\O)/C(CN(C)C)=N/O
c: CCCCn1nnc(NC(=O)COc2ccc(Cl)c(C)c2)n1
Answer: c. CCCCn1nnc(NC(=O)COc2ccc(Cl)c(C)c2)n1
