Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : Forelimbs of human and bats are homologous.
Reason R : Forelimbs of humans and bats have similar anatomical structure.
In the light of the above statements, choose the most appropriate answer from the options given below :
Assertion A : Forelimbs of human and bats are homologous.
Reason R : Forelimbs of humans and bats have similar anatomical structure.
In the light of the above statements, choose the most appropriate answer from the options given below :
Options
- A is false but is true
- BBoth and are correct and is the correct explanation of
- CBoth and are true, but is not the correct explanation of
- D is true but is false
Correct answer
B. Both and are correct and is the correct explanation of
Step-by-step solution
Homologous organs are those which have the same fundamental anatomical structure and embryonic origin but may perform different functions.
The forelimbs of humans and bats have the same basic structural plan, consisting of the humerus, radius, ulna, carpals, metacarpals, and phalanges. Because they share this similar anatomical structure, they are classified as homologous organs.
Thus, Assertion A is true, Reason R is true, and Reason R is the correct explanation for Assertion A.
Answer: Both and are correct and is the correct explanation of
