Four students P, Q, R and S differently reported the following set of organs to be analogous :
P. Forelimb of a frog and forelimb of a lizard
Q. Forelimb of a bird and forelimb of a human
R. Wings of a parrot and wings of a butterfly
S. Wings of a bird and wings of a bat
The two students who have reported correctly are :
(A) P and Q
(B) Q and R
(C) R and S
(D) P and S
Organs that are different in origin but similar in function are known as analogous organs.
Examples of analogous organs are:-
(i) Wings of a parrot and wings of a butterfly
(ii) Wings of a bird and wings of a bat
Thus, the two students who have reported correctly are R and S.
Hence, the correct option is C.
