The correct answer is C. A piece of.

1. A few: This option is typically used with countable nouns (e.g., a few books, a few cars). "News" is an uncountable noun, so "a few" is not appropriate in this context.

2. Many: This option is also used with countable nouns (e.g., many articles, many reports). Since "news" is uncountable, "many" does not fit.

3. A piece of: This phrase is used with uncountable nouns to refer to a single item or segment of something that cannot be easily counted. "A piece of news" correctly fits the context, as it refers to a specific item of information.

4. Mucher: This is not a standard English word. The correct comparative form for uncountable nouns is "more" (e.g., more news), not "mucher."

Summary:

- C. A piece of is the correct choice because "news" is an uncountable noun and requires a phrase like "a piece of" to describe a specific item or segment of news.
