The appraisal process which allocates a percentage of a property’s total value to the land and a percentage to the improvements is known as:

Option A describes 'the ratio of total value to site value,' which is a mathematical relationship or formula, not the name of an appraisal methodology — calling it a named approach misidentifies what is actually just a computational step within the allocation method.

Option C ('Both A and B') is incorrect because Option A is not a named appraisal approach — it merely describes a ratio calculation — so combining it with the correct term in Option B does not create a more complete or accurate answer.

Option D ('Neither A nor B') is incorrect because Option B is precisely the correct term for this appraisal process, making 'neither' a factually wrong choice.
