I think it is not correct because they didn't follow the unit for the given option..it is meant to be in meters but the solved and got their answer in cm
So I suggest the answer is 2.50m

We may also use this if we intend
P=1/f
Then substitute the parameters

Why is the answer 0.25 when it is supposed to be 2.50
