  3. Only D

  4. All of these

C Correct answer
Explanation

Lysosomes are correctly marked by acid phosphatase, peroxisomes by catalase, and mitochondria by cytochrome oxidase. However, SER (smooth endoplasmic reticulum) is associated with detoxification enzymes and lipid synthesis, not amino acid permease, which is a plasma membrane transport protein. Therefore, only pair D is mismatched.
