Concept:Language is a rule-governed system shared by a group, and it naturally includes various regional dialects.
Explanation:A dialect is a regional variety of a language, differing in sound, vocabulary, or grammar.
For example, Hindi spoken across India has many dialects like Bhojpuri, Rajasthani, etc.
Similarly, Telugu spoken in Telangana includes many Hindi‑Urdu words.
A language does not need a script or a specific region to exist; many languages are spoken without a script.
Also, one dialect cannot contain many languages; instead, one language contains many dialects.
Hence, among the given options, only the statement that a language has many dialects is correct.
Answer:D. A language has many dialects.
