Step 1: Understanding myeloid lineage.
The myeloid lineage includes cells such as erythrocytes, macrophages, and granulocytes. These cells develop from hematopoietic stem cells in the bone marrow. T and B lymphocytes, on the other hand, develop from the lymphoid lineage.
Step 2: Analyzing the options.
(A) Macrophages: Correct — Macrophages develop from the myeloid lineage.
(B) T lymphocytes: Incorrect — T lymphocytes develop from the lymphoid lineage.
(C) B lymphocytes: Incorrect — B lymphocytes also develop from the lymphoid lineage.
(D) Erythrocytes: Incorrect — Erythrocytes develop from the myeloid lineage.
Step 3: Conclusion.
The correct answer is (A) Macrophages, as they develop from the myeloid lineage.
