Answer: The correct option is (B) K ∩ L ∩ M.
Step-by-step explanation: We are given to select the correct statement that describes the shaded region shown in the Venn-diagram.
From the Venn-diagram, we see that
there are three sets K, L and M represented as three circles.
We know that in a Venn-diagram, the area that is covered by two circles represents the common parts of both the sets.
So, the shaded region will represent the part that is common to all the three sets K, L and M.
Therefore, the shaded region is the intersection of the three sets L, L and M.
Thus, the shaded region describes K ∩ L ∩ M.
Option (B) is CORRECT.
