Question

acute (sudden or severe) + lympho (lymph) + blast (immature) + ic (pertaining to) + leuk (white) + emia (blood condition) = sudden onset of a cancer of the white blood cells characterized by the overproduction of immature white blood cells (lymphoblasts)

acute (sudden or severe) + lympho (lymph) + blast (immature) + ic (pertaining to) + leuk (red) + emia (blood condition) = sudden onset of a cancer of the red blood cells characterized by the overproduction of immature red blood cells (lymphoblasts)

acute (persistent, long - lasting) + lympho (lymph) + blast (immature) + ic (pertaining to) + leuk (white) + emia (blood condition) = slowly developing cancer of the white blood cells characterized by the overproduction of immature white blood cells (lymphoblasts)

acute (persistent, long - lasting) + lympho (lymph) + blast (immature) + ic (pertaining to) + leuk (red) + emia (blood condition) = slowly developing cancer of the red blood cells characterized by the overproduction of immature red blood cells (lymphoblasts)

Explanation:

The term "acute lymphoblastic leukemia" involves "acute" meaning sudden or severe, "lympho" related to lymph, "blast" indicating immature cells, "ic" (pertaining to), "leuk" meaning white, and "emia" (blood - condition). It is a cancer of white blood cells with over - production of immature white blood cells (lymphoblasts).

Answer:

The first option: acute (sudden or severe) + lympho (lymph) + blast (immature) + ic (pertaining to) + leuk (white) + emia (blood condition) = sudden onset of a cancer of the white blood cells characterized by the overproduction of immature white blood cells (lymphoblasts)
