Answer 1

Answer: (D)

Both B and C

In a eukaryotic cell, DNA is also present in organelles like mitochondria and chloroplasts in addition to the nucleus. The DNA present in organelles resembles prokaryotic DNA. It is circular and devoid of histone proteins unlike the DNA present in nucleus which is linear and is wound around histone protein core. The mitochondrial DNA is a double stranded molecule.

So, the correct answer is 'Both B and C'.
