Question

Directions: Choose the correct option:

Assertion $\left(A\right):$ The amphibians also possess lateral line sense organs particularly in larval stages.

Reason $\left(R\right):$ Amphibians undergo metamorphosis.

• A. Both assertion$\left(A\right)$ and reason$\left(R\right)$ are true and reason$\left(R\right)$ is the correct explanation for assertion$\left(A\right).$
• B. Assertion$\left(A\right)$ is true and reason$\left(R\right)$ is false.
• C. Both assertion$\left(A\right)$ and reason$\left(R\right)$ are true, but reason$\left(R\right)$ is not the correct explanation for assertion.
• D. Assertion$\left(A\right)$ is false and reason$\left(R\right)$ is true.

Answer 1

The correct option is C Both assertion$\left(A\right)$ and reason$\left(R\right)$ are true, but reason$\left(R\right)$ is not the correct explanation for assertion.

Correct option: $\left(b\right)$Both assertion$\left(A\right)$ and reason$\left(R\right)$ are true, but reason$\left(R\right)$ is not the correct explanation for assertion.

$\bullet$ Lateral line system is a system of tactile sense organs that serves to detect movements and pressure changes in the surrounding water.

$\bullet$ This is usually present in aquatic vertebrates and aquatic larval stages of amphibians.

$\bullet$ Larval form of amphibians is aquatic; thus, it possesses the lateral line sense organ just like fishes.

$\bullet$ Amphibians show metamorphosis, a striking change of form or structure in an individual after birth.

$\bullet$ So the correct answer is $\left(b\right)$
