The Trapezoidal rule of volumes V of an embankment divided into a number of sections equidistant D, is given by

A.   V = D [(A_1 + A_n)/(2)  A_2 + A_3 + .................+ A_(n - 1)]
B.   V = D/2  [(A_1 + A_n)/(4)  A_2 + A_3 + .................+ A_(n - 1)]
C.  V = [A_1 + A_n + 2(A_2 + A_4 + ........+ A_(n -1) + 4(A_3 + A_5 + .......+ A_(n-2))]
D.  V = [A_1 + A_n + 4(A_2 + A_4 + ........+ A_(n -1) + 4(A_3 + A_5 + .......+ A_(n-2))]
