My mistake A?

The sentence that is punctuated correctly is option D: "The president lives at 1600 Pennsylvania Avenue NW, Washington DC 20500."

To determine the correct answer, let's look at the specific rules of punctuation for each option:

A) On January 1, 2019 most of the charity's activities will cease.
This sentence uses a comma after the day of the month, which is correct. However, it should not include a comma before the year. The correct punctuation would be "On January 1, 2019, most of the charity's activities will cease."

B) Most of the charity's activities will cease in January 2019.
This sentence does not contain any specific punctuation errors. However, it does not mention the day on which the activities will cease. While the sentence is grammatically correct, option B does not provide a complete date.

C) The president live at 1600 Pennsylvania Avenue, NW, Washington, DC, 20500.
This option contains multiple punctuation errors. It includes commas after "Avenue" and "DC" where they are unnecessary. Additionally, the zip code "20500" should not be separated by a comma from the city and state. The correct punctuation would be "The president lives at 1600 Pennsylvania Avenue NW, Washington DC 20500."

D) The president lives at 1600 Pennsylvania Avenue NW, Washington DC 20500.
This option is punctuated correctly. It includes the proper use of commas in the address and does not include unnecessary commas. The punctuation at the end of the sentence is also correct.

Therefore, the only sentence correctly punctuated is option D: "The president lives at 1600 Pennsylvania Avenue NW, Washington DC 20500."

No, sorry.
