• C. ER
• D. lysosomes

Answer 1

Answer: (A)

cytoplasm

Answer 2

The cellular respiration first takes place in the cytoplasm. Golgi bodies are complex organelles made of membrane-linked stack of cisternae, network of tubules, vesicles and vacuoles which was first seen by George $(1867)$ but studied by Camillo Golgi in $1898$ in nerve cells. Endoplasmic reticulum is a system d membrane lined channels found in all eukaryotes. It constitutes more than $30-60\%$ of total cell membranes. ER is often connect with outer membrane of nuclear envelope. Lysosomes are small vesicles ($0.2-0.8\,\mu m$ containing hydrolysing enzymes ass surrounded by single membrane. They are formed by Golgi apparatus and contain some $40$ types of acid hydrolases.
