Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.000\% 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 additional words.
Options:
a CC1CCCC2(C1)NC(=S)N(c1ccccc1)N2
b CC(=O)c1cccc(NC(=O)c2ccc(C(=O)Nc3cccc(C(C)=O)c3)nc2)c1
c CC(C)Cc1ccc(C(C)C(N)=Nc2ccc(O)cc2)cc1.Cl
Answer: b. CC(=O)c1cccc(NC(=O)c2ccc(C(=O)Nc3cccc(C(C)=O)c3)nc2)c1
