B Correct answer
Explanation

Diapedesis is the key characteristic of leucocytes (white blood cells) - the ability to squeeze through capillary walls and migrate into tissues to fight infection or inflammation. WBCs are nucleated (unlike RBCs), many are granular (not agranular), and they're typically colorless (stains are used to see them).
