Which of the following cell types is present in the lowest amount within a typical blood sample?
Lymphocytes
Basophils
Eosinophils
Neutrophils
Erythrocytes
The Correct Answer is B
A. Lymphocytes: Lymphocytes are a common WBC population (around 20–40% of WBCs), not the lowest.
B. Basophils: Basophils are the rarest WBC type (usually <1% of WBCs) and thus present in the lowest amount.
C. Eosinophils: Eosinophils are low relative to neutrophils but are typically more numerous than basophils (about 1–4% of WBCs).
D. Neutrophils: Neutrophils are the most abundant WBC in normal peripheral blood (40–70% of WBCs).
E. Erythrocytes: Red blood cells are by far the most numerous cells in blood, not the least.

Correct Answer is D
Explanation
A. regeneration: Regeneration replaces lost cells with the same cell type (restores normal tissue) and usually does not produce a scar when full regeneration occurs.
B. remodeling: Remodeling is the maturation and reorganization of the repair tissue (collagen), which shapes the scar but is part of the healing process rather than the initial cause of scarring.
C. granulation: Granulation tissue is rich in new capillaries and fibroblasts and is a stage in healing that precedes scar formation, but granulation itself is not the final scar.
D. fibrous connective tissue repair: Scar formation results from replacement of normal tissue by fibrous (collagenous) connective tissue-i.e., fibrous connective tissue repair (repair rather than regeneration).
