Detailed explanation-1: -Although estimates vary from lab to lab, here are some typical normal ranges for the main parts of the CBC: Red blood cell (RBC) count: 3.93 to 5.69 million cells per cubic millimeter (million/mm3)
Detailed explanation-2: -Complete answer: The RBC count in an adult man per $ mm ^ 3 $ of blood is 4, 600, 000-5, 000, 000. In females, the count is 4, 200, 000-5, 000, 000 per cubic mm of blood.
Detailed explanation-3: -Women usually have a lower RBC count than men, and the level of red blood cells tends to decrease with age. A normal RBC count would be around: men – 4.0 to 5.9 x 10*12/L. women – 3.8 to 5.2 x 10*12/L.
Detailed explanation-4: –The normal value of RBC count ranges between 4 and 5.5 million/cubic mm of blood. In adult males, it is 5-5.5 million/cubic mm and in adult females, it is 4.5-5.5 million/cubic mm. So, the answer is B. In man, the number of RBC per cubic mm of blood is 5 to 5.4 million.
