2 Blue socks, 4 white socks, 6 black socks and 8 red socks.

Question is asking what is the worst case scenario to get matching socks?

Since there are 4 colors, if you draw 4 socks, worst case scenario is you could still have 1 sock per color and not have a match.

Therefore, upon drawing the 5th sock, you will definitely have a match since the 5th sock will form a least a pair with the 1st 4

So 4+1 = 5

Ans: B
