Show Hint
Like most legumes, cowpea is rich in lysine but relatively deficient in sulfur-containing amino acids (methionine and cysteine). It pairs nutritionally with cereals.

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Vegetable cowpea (Vigna unguiculata subsp. sesquipedalis or unguiculata) is an important leguminous vegetable valued for its tender green pods, high protein content, and nutritional quality.
Step 2: Detailed Explanation:
- Statement (I) is true: In vegetable cowpea pods, the carbohydrates consist of both soluble sugars (monosaccharides/disaccharides) and storage carbohydrates (polysaccharides such as starch and dietary fibers). The structural and storage polysaccharides dominate the dry matter of the pods compared to free monosaccharides, resulting in a higher polysaccharide-to-monosaccharide ratio.
- Statement (II) is true: Cowpea protein is of high nutritional quality. Its amino acid profile shows that essential amino acids—particularly lysine, leucine, and phenylalanine—are present in relatively high amounts compared to many cereal crops, making it an excellent dietary supplement.
Consequently, both Statement (I) and Statement (II) are true.
Step 3: Final Answer:
Both Statement (I) and Statement (II) are true.
