    Option D. 649 cm² is the correct option.

    Step-by-step explanation:

    Since surface area of a rectangular prism is calculated by the formula

    Surface area = 2 (length*width + width*height + length*height)

    = 2 (8*13 + 13*10.5 + 8*10.5)

    = 2 (104 + 136.5 + 84)

    = 2 (324.5)

    = 649 cm²

    Therefore, Option D. 649 cm² is the correct option.
