Task: Answer the multiple choice question.
Query: Which drug exhibits a -1.680% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CC(C)N1CCC(N2CCN(CCCn3cccn3)CC2CCO)CC1
b: CCC(C)N(C(=O)COC(=O)c1[nH]c(C)c(C(C)=O)c1C)C1CCS(=O)(=O)C1
Answer: b. CCC(C)N(C(=O)COC(=O)c1[nH]c(C)c(C(C)=O)c1C)C1CCS(=O)(=O)C1
