Explanation:
Detailed explanation-1: -A white blood cell, also known as a leukocyte or white corpuscle, is a cellular component of the blood that lacks hemoglobin, has a nucleus, is capable of motility, and defends the body against infection and disease.
Detailed explanation-2: -Mammal red blood cells (erythrocytes) contain neither nucleus nor mitochondria.

However, nucleus is too small to hinder erythrocyte deformation.
