Best Answer Explained in Below-:

The correct answer is **C: He was hanged for murder.** This choice uses the verb "hanged," which is the appropriate past tense form of "hang" when referring to execution by noose. In English, "hang" has two distinct meanings depending on the context: when referring to hanging objects (like a painting), the past tense is "hung," while in the context of execution, the proper term is "hanged."

Let's analyze the other options:

- **A: He had hanged for murder** is incorrect. The past perfect tense "had hanged" suggests he performed the action of hanging someone else, not that he himself was executed.

- **B: He has been hunged for murder** is also incorrect. The word "hunged" is not a proper form in English; the correct present perfect form should use "hanged."

- **D: He was hunged for murder** is similarly flawed. Again, "hunged" is not a recognized form.

Thus, option C is the only grammatically correct choice that accurately conveys the execution context, using "hanged" appropriately.
