Solution

The correct option is D Peroxisome
Peroxisomes are membrane borne cell organelles, occurring in the cytoplasm of almost all eukaryotic cell.
It contains the reducing enzyme catalase and usually some oxidases.
Hence when a student coming out cell fractionation of tissue and forgot to label his tubes. The contents of one tube when studied showed organelles bounded by the membrane with an activity of catalase enzyme. These organelles could be Peroxisomes.
So, the correct answer is 'Peroxisomes'.
