D

Verified step by step guidance1
Understand the concept of nitrogen balance: Nitrogen balance refers to the balance between nitrogen intake (primarily from dietary protein) and nitrogen excretion (through urine, feces, sweat, etc.). It is an important measure of protein metabolism in the body.
Define negative nitrogen balance: Negative nitrogen balance occurs when nitrogen excretion exceeds nitrogen intake. This indicates that the body is losing more nitrogen than it is gaining, which can happen during conditions like malnutrition, illness, or trauma.
Eliminate incorrect options: Review the provided options and eliminate those that do not match the definition of negative nitrogen balance. For example, 'A condition in which nitrogen intake exceeds nitrogen excretion' describes positive nitrogen balance, not negative nitrogen balance.
Compare the correct definition: Match the definition of negative nitrogen balance ('A condition in which nitrogen excretion exceeds nitrogen intake') with the options provided to identify the correct answer.
Conclude with the correct choice: Based on the definition and comparison, the correct answer is 'A condition in which nitrogen excretion exceeds nitrogen intake.'
