Task: Answer the multiple-choice question.
Query: What is the human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM of a drug with the SMILES CCN(C(=O)CCN1C(=O)c2ccccc2S1(=O)=O)c1ccccc1?
Constraint: You must return none, one or more options from a, b, c, or d without using any additional words.
Options:
a: -16.641
b: 12.985
c: -6.385
d: 12.403
Answer: a. -16.641%.
