Study the given pattern carefully and select the number that can replace the question mark (?) in it.

Logic: (Sum of the value of upper 2 triangle) $$\div$$ 2 = Value of lower triangle

In 1st:

(6 + 4) $$\div$$ 2 = 5

10 $$\div$$ 2 = 5 

In 2nd:

(4 + 8) $$\div$$ 2 = 6

12 $$\div$$ 2 = 6

(8 + 0) $$\div$$ 2 = ?

8 $$\div$$ 2 = ?

In 4rh:

(0 + 6) $$\div$$ 2 = 3

6 $$\div$$ 2 = 3

3 = 3
In 5th:
(6 + 4) $$\div$$ 2 = 5 

10 $$\div$$ 2 = 5 

5 = 5
Thus, the correct option is (b) 4
