Solution
The correct option is A Colchicine
Colchicine is a toxic chemical that is often used to induce polyploidy in plants. Basically, the colchicine prevents the microtubule formation during cell division, thus, the chromosomes do not pull apart like they normally do. The end result is a cell that now has double the number of chromosomes that it would normally have. If this cell divides again in the future, then the doubled number of chromosomes are passed to the offspring cells. Thus, option A is correct. Irradiation, mutagenic substances and ethylene do not induce polyploidy. Thus, the correct answer is option A.
