can someone explain why the answer for 19 is A and why the answer for 20 is A

Q19. The table provides information for the anti-codon of tRNA for each amino acid, and we need the DNA base triplet that codes for each amino acid.

Q20. Point D and B could be eliminated since blood leaving an active muscle is deoxygenated blood. When blood leaves an active muscle the pH decreases due to CO2 dissolved in the blood.

thank you!!

Just to add on, hemoglobin's binding affinity with oxygen decreases as the level of carbon dioxide increases (blood near active muscles). Hence, the saturation of haemoglobin by oxygen is lower (less oxyhaemoglobin and more carbaminohaemoglobin). Hence A is the answer and not B.
