Correct option is A)

  • Microsome fraction is obtained by ultracentrifugation of cell contents. 
  • When post-mitochondrial supernatant is subjected to a centrifugal force of 50000 x g for two hours; the microsomal fraction settles down. 
  • The fraction includes microsomes, endoplasmic reticulum, Golgi bodies etc. 
  • Microsomes are broken pieces of ER often with attached ribosomes.
