Which one of the following correctly explains the function of a specific part of a human nephron?

Which of the following statements are correct for transport of carbon dioxide ?
(i) Nearly 20-25 per cent of CO₂ is transported by RBCs as carbamino-haemoglobin.
(ii) 70 percent CO₂ is carried as bicarbonate.
(iii) About 7 per cent of CO₂ is carried in a dissolved state through plasma.
(iv) Binding of carbon dioxide with haemoglobin is related to the partial pressure of CO₂
(v) pO₂ is a major factor which could affect binding of carbon dioxide with haemoglobin.
(vi) When pCO₂ is low and pO₂ is high as in the tissues, more binding of carbon dioxide occurs whereas.
(vii) When the pCO₂ is high and pO₂ is low as in the alveoli, dissociation of CO₂ from carbamino- haemoglobin takes place.
(viii) Every 100 ml of deoxygenated blood delivers approximately 4 ml of CO₂ to the alveoli.
