Task: Answer the multiple choice question.
Query: Which compound exhibits a -26.274\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a Cl.O=C(CNCC1CCCCC1)Nc1ccc(OC(F)(F)F)cc1
b COc1cc2c(cc1OC)C(COc1ccc([N+](=O)[O-])cc1)N(C(C)=O)CC2
Answer: a. Cl.O=C(CNCC1CCCCC1)Nc1ccc(OC(F)(F)F)cc1
