Identify the correct option:

Vessel	Renal vein	Pulmonary artery	Hepatic portal vein	Main Aortic arch
$(a)$	$PO_2 = 95 \, mm \, Hg, PCO_2 = 40 \, mm \, Hg$	Less concentration of ions in blood	More fatty acid and glycerol in the blood	$PO_2 = 95 \, mm \, Hg, PCO_2 = 40 \, mm \, Hg$
$(b)$	Blood $pH = 7.4$	Less excretory substances than other blood vessels	More nutritive substances	More oxygen than pulmonary artery
$(c)$	Less excretory wastes	$PO_2 = 40 \, mm \, Hg, PCO_2 = 45 \, mm \, Hg$	Less amount of fatty acid and glycerol compare to other blood vessels	More excretory substances than renal vein
$(d)$	More oxygen than pulmonary artery	More excretory waste than renal vein	$PO_2 = 95 \, mm \, Hg, PCO_2 = 40 \, mm \, Hg$	Less excretory waste than hepatic portal vein
