Concept:
The Shrimad Bhagavad Gita begins with a dialogue on the battlefield of Kurukshetra. The first verse is spoken by King Dhritarashtra, who asks Sanjaya about the events taking place in the battlefield.
The main body of the Bhagavad Gita later develops as a dialogue between Arjuna and Shri Krishna, where Krishna answers Arjuna's doubts and spiritual questions.
Step 1: Analyze Assertion A.
Assertion A states:
\[
\text{In the first shloka of Bhagavad Gita, Dhritarashtra asks questions to Sanjaya.}
\]
This statement is true.
The first verse is:
\[
\textit{Dharmakshetre Kurukshetre samavetā yuyutsavaḥ}
\]
where Dhritarashtra asks Sanjaya:
\[
\text{``What did my sons and the Pandavas do?''}
\]
Step 2: Analyze Reason R.
Reason R states:
\[
\text{In Bhagavad Gita, Shri Krishna answers the questions of Arjuna.}
\]
This statement is also true because the Gita mainly consists of Krishna's teachings given in response to Arjuna's confusion and questions.
Step 3: Examine the relationship between A and R.
Although both statements are true:
• Assertion A refers to the opening dialogue between Dhritarashtra and Sanjaya.
• Reason R refers to the later philosophical dialogue between Krishna and Arjuna.
The Reason does not explain why Dhritarashtra questioned Sanjaya in the first shloka.
Therefore:
\[
\text{R is not the correct explanation of A}
\]
Step 4: Identify the correct option.
Since both A and R are true, but R does not correctly explain A, the correct answer is:
\[
\boxed{\text{Both A and R are true but R is NOT the correct explanation of A}}
\]
