Number of $CO_2$ molecules released in glycolysis is $:-$

Which of the following statements ($i$ to $v$) regarding glycolysis are correct?
$(i)$ It is ten enzymatic reactions that convert a six-carbon molecule to a three-carbon pyruvate and result in a net gain of $2\, ATP$ molecules.
$(ii)$ Glucose undergoes partial oxidation to form one molecule of pyruvic acid.
$(iii)$ Glucose is phosphorylated to give rise to glucose-$6$-phosphate by the activity of the enzyme phosphofructokinase.
$(iv)$ The scheme of glycolysis was given by Gustav Embden,Otto Meyerhof,and $J$. Parnas and is often referred to as the $EMP$ pathway.
$(v)$ $ATP$ is utilized at two steps: first in the conversion of glucose into glucose-$6$-phosphate and second in the conversion of fructose-$6$-phosphate to fructose-$1,6$-bisphosphate.

During respiration,pyruvic acid is formed from which of the following processes?
