**Concept:** The question tests on the basics of Counting

**Solution**

When seating n people in a circle the number of arrangements = (n - 1)!

Let the 2 people be considered as 1 unit. We therefore have 5 units (4 individuals and 1 unit of 2 people) to be arranged.

External arrangement = (5 - 1)! = 4! = 24

Internal arrangement of the 2 people = 2! = 2

Total arrangements = 24 * 2 = 48**Option B**
