The Correct Option is A
Solution and Explanation
Concept:
Proteins are organic compounds made up of amino acids. They contain carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. On average, proteins contain approximately \(16\%\) nitrogen by weight. This fact is widely used in biochemistry and nutrition to estimate protein content using nitrogen analysis.
Step 1: Recall the standard nitrogen content in proteins.
The average percentage of nitrogen present in proteins is: \[ 16\% \]
Step 2: Identify the correct option.
Among the given options: \[ 16 \] is the correct answer. Hence, the correct option is: \[ \boxed{(A)\ 16} \]
