The first stage of cellular respiration (glycolysis) occurs in
a. inner mitochondrial membrane
b. cytoplasm
c. mitochondrial matrix
d. nucleus

Option B. Cytoplasm  

Explanation:

Cellular respiration is defined as the process in which sugar break down take place into as form and utilized by cell in the form of energy. In Cellular respiration food is utilized to create ATP and further used as energy source by using oxygen, and named aerobic respiration

There are four stages of cellular respiration includes first is glycolysis, second is pyruvate oxidation, third is citric acid cycle, and forth is oxidative phosphorylation.

Glycolysis is the first stage of cellular respiration which takes place in cytoplasm or cytosol.

In the process of Glycolysis six-carbon sugar undergo chemical changes and converted into two pyruvates, each containing three-carbon organic molecule. ATP and NADH are formed in this reaction.

Hence, the process take place in cytoplasm.
