2n=26
divide both sides by 2
n=13

Empirical data are gathered from experiments. This does not hold true for all species at all times. But the only way to know a certain datum for a certain specie at a certain situation, you do an experiment. However, theoretical data is more on the theory or concept of the situation. It formulates a general equation that could as much as possible hold true to all.
Therefore, this data is empirical.
The answer is A.
