Adi shankara had a very short life span in which he propagated the ways of leading a righteous life . This 32 years are from ___ to __ ?

Adi Shankaracharya was born in 788 CE and died in 820 CE, living exactly 32 years. This timeframe is well-established in traditional biographies and scholarly consensus. During this brief period, he wrote commentaries on major Upanishads, the Bhagavad Gita, and Brahmasutras, established four mathas, and revived Advaita Vedanta. Option A (712-834 CE) is too early. Option C (1040-1072 CE) is much too late - more than two centuries after his time. Option D (9 BC to 23 AD) is completely incorrect and places him in the wrong millennium.
