Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 7.949\% 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 additional words.
Options:
a: CCOc1ccc(NC(=O)CSc2nnc(C34CC5CC(CC(C5)C3)C4)n2C)cc1
b: CCSc1cnn(-c2ccccc2)c(=O)c1SCC
c: CC1=C(C#N)C(c2ccccc2O)C(C#N)=C(C)N1
Answer: b. CCSc1cnn(-c2ccccc2)c(=O)c1SCC
