Step-by-step explanation:

Are the volumes equal?      No, so throw out the first and the last one.

Is the volume of the pyramid greater than the volume of prism?  

                                            No, so throw out the third one

so by inspection it must be the remaining one

or mathematically

    vol pyramid = (1/3)(base)(height)

    vol prism     =  (base)(height)

              vol pyramid   /   vol prism      

           (1/3)(base)(height) / (base)(height)   = 1/3

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)
