Task: Answer the multiple choice question.
Question: Which drug has a 6.902\% human ether-à-go-go related gene (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 CCS(=O)(=O)Nc1ccc(C2=NN(C(=O)c3ccco3)C(c3ccc(C)cc3)C2)cc1
b CCNc1nc(SCc2ccccc2)nc(N2CCOCC2)n1
c CCOC(=O)c1ccc(N2CSC3=C(C#N)C(c4ccc(OC)cc4OC)CC(=O)N3C2)cc1
Answer: b. CCNc1nc(SCc2ccccc2)nc(N2CCOCC2)n1
