Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -7.730\% 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: NC(=O)c1cc2ccccc2o/c1=N/NC(=O)c1cccs1
b: C=CCN1C(=O)C(CC(=O)O)SC1=Nc1ccc(N=Nc2ccccc2)cc1.N
c: Cc1cc(C)c(NC(=O)COc2ccc(-n3cnnn3)cc2)c(C)c1
Answer: a. NC(=O)c1cc2ccccc2o/c1=N/NC(=O)c1cccs1
