A.
Calvin cycle
B.
EMP pathway
C.
Hatch and Slack pathway
Answer
D.
TCA cycle

Answer: Option C

Solution

Answer: Option C
Solution:
Sugarcane shows the high efficiency of CO2 fixation because it performs Hatch and Slack pathways.
C4 plants including maize, sugarcane, and sorghum avoid photorespiration by using another enzyme called PEP during the first step of carbon fixation.
This step takes place in the mesophyll cells that are located close to the stomata where carbon dioxide and oxygen enter the plant.
