Given below are two statements, one labeled as Assertion (A) and the other as Reason (R). **Assertion (A):** King Lakshmanasena abandoned his capital Nadia and fled to eastern Bengal (Vikramapura) when Bakhtiyar Khalji raided the city with a small cavalry force. **Reason (R):** The Sena military apparatus was highly decentralized, and the sudden, swift nature of the Turkish cavalry raid caught the palace guards completely off-guard without any organized defense. Select the correct answer using the codes given below:

Options:

• A: Both (A) and (R) are true and (R) is the correct explanation of (A).
• B: Both (A) and (R) are true but (R) is not the correct explanation of (A).
• C: (A) is true but (R) is false.
• D: (A) is false but (R) is true.
