  • Correct answer
    C
    If the assertion is true but the reason is false.
  • D
    If both assertion and reason are false.

Plasmids are found mostly in prokaryotic cells and yeasts. They do not form a part of the normal chromosomal DNA of a cell and are capable of replicating independently. They constitute extrachromosomal DNA.

Hence, the correct answer is option: 'C'.
