Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.873\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C(Cn1cc(C(F)(F)F)ccc1=O)N/N=C/c1ccc(F)cc1
b Cn1nc(N)c2c1N=P(N1CCOCC1)(N1CCOCC1)N=C2c1ccccc1
Answer: a. O=C(Cn1cc(C(F)(F)F)ccc1=O)N/N=C/c1ccc(F)cc1
