Explanation:

Among the given options, 'प्रेयसि' is the correctly spelled word, meaning beloved or dear one. Option A should be 'कृशांगी' (slender-bodied). Option B 'चातकिनी' is incorrect; the correct word for a female Chatak bird is 'चातकी'. Option C 'कोमलांगिनी' is incorrect; it should be 'कोमलांगी' (soft-bodied). Thus, 'प्रेयसि' is the only word spelled accurately.
