Step 1: Understanding the Concept:
Botanical nomenclature (scientific names) of major pulse crops is a fundamental topic in agricultural sciences.
Matching these with their common English names helps in establishing precise botanical identity.
Step 2: Detailed Explanation:
Let us match each scientific name with its common name:
1. Cicer arietinum (L): This is the scientific name of Chickpea (also commonly known as Bengal gram or Gram). It is the most dominant pulse crop in India. Thus, (A) matches with (III).
2. Cajanus cajan (L): This is the scientific name of Pigeon pea (also known as Arhar or Red gram). It is a major Kharif pulse crop. Thus, (B) matches with (IV).
3. Vigna mungo (L): This is the scientific name of Black gram (commonly known as Urd bean). Thus, (C) matches with (I).
4. Lens culinaris: This is the scientific name of Lentil (commonly known as Masur). Thus, (D) matches with (II).
This pairing perfectly corresponds to: (A) - (III), (B) - (IV), (C) - (I), (D) - (II).
Step 3: Final Answer:
Therefore, the correct matching option is (B).
