**Answer:** B

**Solution:**

Starting from 4th quadrant in anticlockwise direction, Subtract one from the sum of squares of both the numbers in outer part of the quadrant to get the value of the number in the inner part of same quadrant.

**4th Quadrant**

= (2 + 8 )² – 1

= 10² – 1

= 100 – 1

= 99

**1st Quadrant**

= (3 + 8)² – 1

= 11² – 1

= 121 – 1

= 120

**2nd Quadrant**

= (7 + 1 )² – 1

= 8² – 1

= 64 – 1

= 63

**3rd Quadrant**

= (5 + 4 )² – 1

= 9² – 1

= 81 – 1

= **80**
