Correct option is D
Karl von Frisch, an Austrian ethologist, was awarded the Nobel Prize in Physiology or Medicine in 1973 (shared with Konrad Lorenz and Nikolaas Tinbergen) for his pioneering work on animal behavior. One of his most notable contributions was decoding the
waggle dance of honeybees. This unique dance is a method of communication bees use to convey the direction and distance of food sources to other members of the hive.
His meticulous observations and experiments demonstrated that the waggle dance contained specific spatial information, effectively proving that bees could communicate in a symbolic way — a groundbreaking discovery in the field of animal behavior and communication.
Explanation of Other Options:
·
(a) Ronald Ross: Awarded the Nobel Prize in 1902 for his work on malaria, particularly for discovering that malaria is transmitted by mosquitoes.
·
(b) C.F. Beason: Not recognized for Nobel-level contributions in bee communication; likely not relevant to this field.
·
(c) Thomas: Ambiguous option — no full name or notable link to bee communication or Nobel Prize in this context.
