Task: Answer the multiple choice question.
Query: Which compound exhibits a -4.492\% 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. CS(=O)(=O)N(CC(=O)N1CCN(Cc2ccc3c(c2)OCO3)CC1)Cc1ccc(Cl)cc1
b. Cc1ccc(S(=O)(=O)N(C)C)cc1NC(=O)COC(=O)c1ccc2c(c1)OCCO2
Answer: a. CS(=O)(=O)N(CC(=O)N1CCN(Cc2ccc3c(c2)OCO3)CC1)Cc1ccc(Cl)cc1
