To find the surface area of a rectangular pyramid, we need to find the areas of the five faces and add them together.
The area of the base is l * w = 8 * 4 = 32 square yards.
The areas of the four triangular faces are calculated using the formula (l * h) / 2. Since there are four identical triangular faces, the total area of the triangular faces is 4 * (8 * 2) / 2 = 32 square yards.
Adding the area of the base and the area of the triangular faces, we get a total surface area of 32 + 32 = 64 square yards.
However, none of the given answer choices match this result. Therefore, none of the provided options make sense as the correct answer.
