To find the probability of picking out a black pair of socks, we need to determine the total number of pairs of socks and the number of black pairs.

The sock drawer has:
- 2 blue pairs
- 4 white pairs
- 4 black pairs

First, let's calculate the total number of pairs:

Total pairs = 2 (blue) + 4 (white) + 4 (black) = 10 pairs

Now, we need to find the probability of picking a black pair:

Probability of picking a black pair = (Number of black pairs) / (Total number of pairs) = 4 / 10

Now we can simplify that fraction:

4 / 10 = 2 / 5

So the probability of picking a black pair is \( \frac{2}{5} \).

Thus, the best answer from the options is:

B \( \frac{2}{5} \)
