Answer:
A 2
Explanation:
Scaling deals with measurements.
for example, the question says, 1 : 44. Assuming we're using cm : m, this is inferring that, 1 centimeter on the model will represent 44 meters in real life. This means, the number of windows in the real tree will be carried down to the model, only the sizes would be reduced.
if a window in the real tree measures 44 meters, then it would be scaled down to be 1 centimeter on the model.
irrespective, models doesn't change the number of features, only the dimensions.
