Task: Answer the multiple choice question.
Query: Which drug exhibits a -12.779% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a COc1ccccc1/C=N/NC(=O)CNC(=O)c1ccc(S(=O)(=O)N(C)C)cc1
b CCC(C)c1cc(S(=O)(=O)N2CCOCC2)ccc1OC
Answer: b. CCC(C)c1cc(S(=O)(=O)N2CCOCC2)ccc1OC
