**Core Concept**
Assessment of nutritional status is crucial in clinical practice to identify malnutrition, which can lead to increased morbidity, mortality, and healthcare costs. Nutritional status can be evaluated through various anthropometric, biochemical, and clinical parameters.

**Why the Correct Answer is Right**
The correct answer is related to the assessment of nutritional status, which involves evaluating body mass index (BMI), mid-upper arm circumference (MUAC), and skinfold thickness. These parameters are used to assess muscle mass and body fat stores. A combination of these parameters can provide a more accurate assessment of nutritional status.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not provide a clear and direct method for assessing nutritional status. Nutritional status assessment involves a combination of various parameters, not just one.
**Option B:** This option is incorrect because while BMI is a useful parameter, it does not provide information about muscle mass or body fat distribution, which are essential for nutritional status assessment.
**Option C:** This option is incorrect because it is a partial truth. While skinfold thickness can provide information about body fat stores, it is not the only parameter used in nutritional status assessment.

**Clinical Pearl / High-Yield Fact**
A combination of anthropometric, biochemical, and clinical parameters is essential for accurate nutritional status assessment. This includes evaluating BMI, MUAC, skinfold thickness, and laboratory tests such as serum albumin and prealbumin levels.
