Concept:
The Bhagavad Gita presents different spiritual paths for liberation.
These paths are suitable for people of different temperaments and capacities.
Step 1: Check Assertion (A).
The Bhagavad Gita teaches different paths such as:
\[
\text{Karma Yoga}
\]
\[
\text{Jnana Yoga}
\]
\[
\text{Bhakti Yoga}
\]
\[
\text{Dhyana Yoga}
\]
So, Assertion (A) is correct.
Step 2: Check Reason (R).
The Reason says that different individuals can choose different paths according to their capacity.
This is also correct.
Step 3: Check explanation.
The Gita teaches multiple paths because people have different natures, abilities and spiritual inclinations.
Thus, Reason correctly explains Assertion.
Hence:
\[
\boxed{\text{(A)}}
\]
