Problem statement: Answer the multiple choice question.
Query: Which drug has a -0.134\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] CCc1nc2c(cnn2-c2ccc(Cl)cc2)c(=O)n1-c1ccc(OC)cc1
[b] CCOc1ccc(N2C(=O)/C(=C\c3ccc(O)c(OC)c3)S(=O)(=O)C2c2cccc([N+](=O)[O-])c2)cc1
Answer: a. CCc1nc2c(cnn2-c2ccc(Cl)cc2)c(=O)n1-c1ccc(OC)cc1
