'Jise jeeta na ja sake' uske liye kavita mein kaun sa shabd prayukt hua hai? (Which word has been used in the poem for 'one who cannot be conquered'?)

The word 'Ajeya' is formed from the prefix 'a' (negation) + 'jeya' (that which can be conquered), literally meaning 'unconquerable' or 'one who cannot be defeated/conquered'. This exactly matches the given definition 'Jise jeeta na ja sake'. 'Akhand' means undivided/unbroken, 'Amar' means immortal, and 'Divya' means divine — none of which carry the specific meaning of being unconquerable. The word appears in the poem in the line 'Yug-yug ajeya, nirbandh, mukt'.
