Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.820\% 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 additional words.
Options:
[a] COc1ccc2c(c1OC)C(=O)OC2Nc1ccc(S(=O)(=O)N=C(N)N)cc1
[b] COc1ccc(NS(=O)(=O)c2ccc(O)c(C(=O)OCC(=O)N3CC(C)OC(C)C3)c2)cc1
Answer: a. COc1ccc2c(c1OC)C(=O)OC2Nc1ccc(S(=O)(=O)N=C(N)N)cc1
