    Eduncle Best Answer

    Rubisco is one of the slowest and largest enzymes, with a molecular mass of 560 kDa. In land plants and green algae, the chloroplast rbcL gene encodes the 55-kDa large subunit, whereas a family of rbcS nuclear genes encodes nearly identical 15-kDa small subunits; in nongreen algae both the rbcL and rbcS genes are chloroplast encoded. So statement B is wrong. Correct combination is A,C and D.
