Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.624\% 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) O=C(COC(=O)CCCN1C(=O)c2ccccc2C1=O)Nc1cc(Cl)cc(Cl)c1
b) Cn1cc(S(=O)(=O)N2CCN(C(=O)c3ccco3)CC2)c(=O)n(C)c1=O
Answer: b. Cn1cc(S(=O)(=O)N2CCN(C(=O)c3ccco3)CC2)c(=O)n(C)c1=O
