got a tad bit confused on question 7 which asks which layer o the hematocrit 'lacks nuclei'.
i picked RBCs only, but their answer says white blood cells also lack nuclei? i was under the impression that some WBCs possess nuclei, or am i wrong?

You're correct

so the answer's wrong?
or is it a case of some WBCs having nuclei and others not having nuclei?😛

Platelets and RBC's lack nuclei. In a hematocrit, the plasma layer and the RBC layer will lack nuclei.
