Normal adult human male has A. 10 gram of haemoglobin/100 gram of blood B. 14 gram of haemoglobin/100 gram of blood C. 18 gram of haemoglobin/100 gram of blood D. 24 gram of haemoglobin/100 gram of blood

The correct answer is B. 14 grams of hemoglobin/100 grams of blood.

Hemoglobin is a protein found in red blood cells that carries oxygen from the lungs to the rest of the body. The normal range of hemoglobin for adult men is 14-18 grams per deciliter (g/dL) of blood. A hemoglobin level below 14 g/dL is considered low, and a level above 18 g/dL is considered high.

There are a number of factors that can affect hemoglobin levels, including:

• Age: Hemoglobin levels tend to decrease with age.
• Gender: Men typically have higher hemoglobin levels than women.
• Height: People who are taller tend to have higher hemoglobin levels than people who are shorter.
• Weight: People who are overweight or obese tend to have lower hemoglobin levels than people who are at a healthy weight.
• Race: African Americans typically have higher hemoglobin levels than Caucasians.
• Certain medical conditions: Hemoglobin levels can be affected by a number of medical conditions, including anemia, sickle cell anemia, and thalassemia.

If you are concerned about your hemoglobin levels, talk to your doctor. They can order tests to determine your levels and help you determine if you need treatment.

Here is a brief explanation of each option:

• Option A: 10 grams of hemoglobin/100 gram of blood is below the normal range for adult men.
• Option B: 14 grams of hemoglobin/100 gram of blood is the normal range for adult men.
• Option C: 18 grams of hemoglobin/100 gram of blood is above the normal range for adult men.
• Option D: 24 grams of hemoglobin/100 gram of blood is significantly above the normal range for adult men.
