B. Colchicine treatment
C. Auxin and cytokinin treatment
D. None of the above

Answer

B

Explanation

Haploids can be converted to normal diploid using colchicine treatment. Colchicine is an alkaloid, often called anaphasic poision as it inhibits the anaphase stage of mitosis by restricting the activities of spindle fibres after longitudinal splitting of chromosomes. Thus poleward movement of chromosomes is inhibited and the number of chromosomes becomes double (chromosomal doubling).
