• B. Protoderm and procambium
• C. Cork cambium and quiescent centre
• D. Quiescent centre and calyptrogen

Answer 1

The correct option is A Root cap and active root meristem

Clowes was able to show that there was a central region in roots of zea where the cytoplasm had the lower content of RNA and where the cells had smaller nucleoli. It lies in between root cap and active root meristem. Thus correct option is A.
