As we have already studied in Chromosomal Number Mutations -

Polyploidy:

  • Polyploidy is a type of mutation that occurs when an individual bears more than one haploid set of chromosomes. 
  • If the individual with polyploidy bears three sets of haploid chromosomes, the condition is said to be triploidy whereas if it has four haploid sets, the condition is said to be tetraploidy.
  • It is of following types:
    • Autopolyploidy: When there is a numerical increase in the same genome.
    • Allopolyploidy: It has developed through hybridization between two species followed by a doubling of chromosomes.
       

 Hence, the correct option is (c).
