• A. B
• B. A
• C. C

Answer 1

The correct option is D D-constant

Solution

If both the partitions, were filled

have lied on the diagonal

of the square. Then if sand is

added into one of the particle

then coal will be shifted

towards sand region as sand

is denser than air, since only

point - D lies in sand region.

Option - D is correct.
