• B. Ribosomes
  
• C. Vacuole
• D. Both A and B

Answer 1

Answer: (D)

Both A and B

Mitochondria are regarded as semi-autonomous organelles, due to the presence of DNA and ribosomes which helps them to synthesisze their own proteins. DNA which is present in the mitochondria is known as mt-DNA and the ribosomes are known as mitoribosomes. The mitochondrial DNA produces its own mRNA, tRNA and rRNA which is translated into protein by the mitribosomes.

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