Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -0.610\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a NC(=O)CC(NC(=O)Cc1cccc2ccccc12)c1ccc(NCCOc2ccccc2)c([N+](=O)[O-])c1
b CC(C)CCNc1cc(=O)n(C)c(=O)n1C
c CC(C)N1CCN(Cc2cccc(-n3cccn3)c2)CC1CCO
Answer: b. CC(C)CCNc1cc(=O)n(C)c(=O)n1C
