Correctly match the names of the plant taxonomists (Group I) with the titles of the books they authored (Group II):
Let's match the plant taxonomists with their books:
- (P) John Hutchinson: Hutchinson is known for his work "The Families of Flowering Plants," which is considered a comprehensive guide to plant taxonomy. Hence, P-4 is the correct match.
- (Q) Adolf Engler and Karl Prantl: This pair authored the classic "Die Natürlichen Pflanzenfamilien," a multi-volume work that describes the natural families of plants. Hence, Q-3 is the correct match.
- (R) Arthur Cronquist: Cronquist is famous for his book "Evolution and Classification of Flowering Plants," which presents a new classification of plants based on evolutionary relationships. Hence, R-2 is the correct match.
- (S) Alfred Barton Rendle: Rendle is known for his book "Classification of Flowering Plants," which is a significant contribution to plant classification. Hence, S-1 is the correct match.
Thus, the correct answer is (A).
