The correct option is A
3

Initially,
Number of Blue balls = 4
And, total number of balls = Number of red balls + Number of blue balls = 5 + 4 = 9.

Now, after one blue ball is removed,
Number of Blue balls = 3
And, total number of balls = Number of red balls + Number of blue balls = 5 + 3 = 8

So, The correct answer is 3 and 8
