But absent a krantz anatomy . Explain in detail.. please right answers only...

Dear student,
Answer is d) both b) and c)
C) is not the option because PEP carboxylase and 
RuBP carboxylase are found in both C4 and CAM plants. Euphorbia is a plant with CAM, C3 and C4 type of photosynthesis. Therefore PEP carboxylase and RuBP carboxylase are found in Euphorbia.

Regards
