• A. $a-2,b-4,c-3,d-1$
• B. $a-3,b-1,c-4,d-2$
• C. $a-3,b-4,c-2,d-1$
• D. $a-4,b-3,c-1,d-2$
• E. $a-3,b-4,c-1,d-2$

Answer 1

The correct option is B $a-3,b-1,c-4,d-2$

• The chloroplast vary considerable in their shape particularly in algae.
• They may be cup shaped (Volvox, chlamydomanas), H-shaped (Chlamydomonas biciliata), girdle shaped (Ulothrix), spiral (Spirogyra), reticulate (Oedogonium), stellate (Zygnema) but normally discoid in most of the other groups.
• Thus, option B is correct.
