To ensure that Melinda has a pair of each color (red, black, and white), we need to consider the worst-case scenario, where she initially removes socks that are the same color.
- She might remove all 3 pairs of red socks first.
- Then, she might remove all 2 pairs of black socks.
- Finally, she would need to remove all 4 pairs of white socks to ensure she has a pair of each color.
So, the minimum number of pairs she must remove from the drawer is 3 (red) + 2 (black) + 4 (white) = 9 pairs.
The correct answer is 9 pairs.
