    A)  Potato          

    B)  Sugarcane

    C)  Wheat          

    D)  Rice

    Correct Answer: B

    Solution :

    \[{{C}_{4}}\] -plants utilise solar energy most efficiently,  because photosynthesis rate is very high in \[{{C}_{4}}\]-plants, eg, sugarcane, maize, etc. In \[{{C}_{4}}\]-plants, carbon fixation occurs in mesophyll cells and carbon dioxide is then concentrated in bundle sheath cells, inhibiting photorespiration and increasing carboxylation efficiency.
