Solution

The correct option is C $240000 c u m$
Area of the base of the brick = length $\times$ width = 8 × 3 = 24 sq m

Height of one column $= 50 m$
Volume of one column = area of the base of the brick $\times$ height of one column
$= 24 \times 50 = 1200 c u m$

Number of columns $= 200$

Volume of all column $= 1200 \times 200 = 240000 c u m$
Hence, the volume of bricks required to build $200$ columns in the building is $240000 c u m .$
