Correct Answer: 80


Solution : In the row, add the square of the first and the third number and the add second number to the resultant number to obtain the fourth number.

In the first row: 3 2 + 5 2 = 9 + 25 = 34 and 34 + 11 = 45
In the second row: 2 2 + 6 2 = 4 + 36 = 40 and 40 + 4 = 44
Similarly, in the third row: 3 2 + 8 2 = 9 + 64 = 73 and 73 + 7 = 80

So, 80 is the missing number in the given figure. Hence, the third option is correct.
