Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.699\% 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 or b without using any other words.
Options:
a: CCC(=NCc1cc(OC)cc(OC)c1)c1c(O)n(C)c(=O)n(C)c1=O
b: CC1CC(C)CN(C(=O)C(C)N2CCN(S(=O)(=O)c3cccs3)CC2)C1
Answer: a. CCC(=NCc1cc(OC)cc(OC)c1)c1c(O)n(C)c(=O)n(C)c1=O
