Task: Answer the multiple choice question.
Query: Which compound exhibits a -25.084% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: Nc1ccc(S(=O)(=O)NC2=NCCCCC2)cc1
b: CCOC(=O)N1CCN(C/C(C)=C/c2ccccc2)CC1
c: O=C(O)CNC1c2ccccc2CSc2ccccc21
Answer: b. CCOC(=O)N1CCN(C/C(C)=C/c2ccccc2)CC1
