The author asserts that language evolution is a natural phenomenon and proof that a language is alive. While acknowledging the need for appropriate language in public settings, the author argues against rejecting new words outright. The correct option correctly reflects this balanced perspective.
The other options are incorrect for the following reasons:
- 'It is natural that young people stop using standard language in daily conversation.': The author supports the creation of new words but does not suggest standard language will or should be abandoned.
- 'Youth slang should be completely eliminated from society.': The author explicitly states that changes shouldn't be uniformly rejected as a 'breakdown.'
- 'Words currently considered incorrect should be actively used.': The text mentions that accurate expression is necessary in public, so indiscriminate active use is not advocated.
