Find the missing characters, if same rule is applied in all the three figures. RWOPRRRRRRWWWWWWOOOOOOPPPPPPARRRRRRRBWWWWWWWCOOOOOOODPPPPPPP?

The correct option is R. The answer option is A → The sum of the numbers in each of the figures gives the position of the alphabet → For example in the 1st figure the sum of the numbers 4, 2 is 6, and F is the 6th alphabet → Similarly in the 2nd figure, the sum of the numbers 8, 3 and 4 is 15, and O is the 15th alphabet → In the final figure the sum of the numbers 7, 8, 3 is 18. Hence the missing alphabet must be the 18th alphabet which is R. Hence the answer.
