Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R)

Assertion (A): The first stage of gametophyte in the life cycle of moss is protonema stage.

Reason (R): Protonema develops directly from spores produced in capsule.

In light of the above statements, choose the most appropriate answer from the options given below.

Option A:
Both $\mathbf{A}$ and $\mathbf{R}$ are correct but $\mathbf{R}$ is NOT the correct explanation of $\mathbf{A}$ .
Option B:
$\mathbf{A}$ is correct but $\mathbf{R}$ is not correct
Option C:
$\mathbf{A}$ is not correct but $\mathbf{R}$ is correct.
Option D:
Both $\mathbf{A}$ and $\mathbf{R}$ are correct and $\mathbf{R}$ is the correct explanation of $\mathbf{A}$ .
Correct

Answer: D

The predominant stage of the life cycle of a moss is the gametophyte which consists of two stages.

The first stage is the protonema stage, which develops directly from a spore. Capsule of the

sporophyte contains spore which gives rise to protonema. Thus, reason correctly explains

the assertion.
