C.

"Billy, my best friend, had a big dinner yesterday."

Why?
Because it correctly uses commas to set off nonessential information ("my best friend"). So, it's not like Billy has multiple best friends, each having their own big dinner. That would be quite the feast!

The sentence that uses punctuation correctly is Option C:

"Billy, my best friend, had a big dinner yesterday."

To determine the correct answer, we need to evaluate the usage of punctuation in each option.

Option A:
"Billy my best friend had, a big dinner yesterday."
In this option, there is a comma after "had," which is not needed. The comma should be placed before "my best friend" to set it off as an appositive phrase. So, this option does not use punctuation correctly.

Option B:
"Billy my best friend had a big dinner yesterday."
This option does not include any punctuation. While this is grammatically acceptable, it could be improved by including punctuation to separate the appositive phrase "my best friend" from the rest of the sentence.

Option C:
"Billy, my best friend, had a big dinner yesterday."
This option correctly uses commas to set off the appositive phrase "my best friend." The sentence is clear and punctuated appropriately.

Option D:
"Billy, my best friend had a big dinner, yesterday."
In this option, there is a comma after "my best friend" that is unnecessary. The comma should be placed after "dinner" to separate the dependent clause "yesterday." So, this option does not use punctuation correctly.

Therefore, Option C is the correct answer as it uses punctuation correctly by placing commas before and after the appositive phrase "my best friend."
