The correct sentence should be: "Kanyakumari is popular for its beautiful beaches, unique Vivekananda Rock Memorial, and stunning sunrise and sunset views."
The error is the use of "view," which should be plural "views" to match "sunrise and sunset."
Using the plural form "views" correctly indicates that both the sunrise and sunset offer separate, beautiful sights.
This ensures parallel structure in the sentence, maintaining grammatical consistency.
Proper agreement between nouns and their descriptors is essential for clarity and accuracy in writing.
Therefore, the plural form enhances the readability and correctness of the sentence.
