Friction depends on the shape of the body as well....the option is incorrect

Ans 3:

Class : Class 6
AND when shape of an object is spherical it undergoes rolling friction and when the shape is a flat surface the moving object undergoes sliding friction which is greater than rolling friction

Ans 4:

Class : Class 9
But if the shape of the object is streamlined then then the force of friction exerted on it will be less

Ans 5:

Class : Class 6
shape of the body affects the drag friction also sliding and rolling friction would be same if shape did not matter.

The correct option is D because there are 4 heaps of cubes and each have 4 cubes so 4 multiplied by 4 = 16 so 16 + the front cubes , there are 10 cubes in one line at up and 10 at bottom so 10 + 10 = 20 + 16 which equals to 36 . Thus it is the correct answer .
