From the additional plates given in the options, which one of the combinations of additional plates would allow the player to construct a five-letter palindrome. The player should use all the five plates exactly once. The plates can be rotated in their plane.

Question 5 Explanation:
From the question we know that letters can rotate in the plane, now we will verify the options one by one.
Option 1: A,D,D,D,J from these letters we can’t form a palindrome.
Option 1: A,D,D,D,J from these letters we can’t form a palindrome.
Option 2: A,D,R,A,R from these we can form RADAR which is a palindrome.
Option 3: A,D,Z,E,D from these letters we can’t form a palindrome.
Option 4: A,D,I,L,Y from these letters we can’t form a palindrome.
Correct Answer: B
