Final answer:
No comma is needed in the sentence "My dad is traveling to New York for work this week" as given in the options. The sentence does not have a dependent clause or a list that would require a comma for separation.
Step-by-step explanation:
The correct placement of a comma in the sentence "My dad is traveling to New York for work this week" would actually be after the word "work" if you wanted to emphasize that the trip was occurring this week, as a form of mild interjection. However, the sentence is also correct without any comma. None of the options provided (A, B, C, D) are traditionally correct comma placements for this particular sentence since the sentence does not contain a dependent clause, nor does it list items in a series. It is a simple statement and doesn't require any commas for clarity or grammatical reasons.
Let's review some other sentences for the correct use of commas:
- I finally found my keys, and I got to work just in time. (Two independent clauses joined by a coordinating conjunction)
- Mrs. Contreras threw out her old coffee table and cleaned the carpet. (No comma needed here because both actions are done by the same subject)
- Taking the elevator to the roof, we hoped we could see the skyline and the bay. (Comma after introductory phrase)
- Though Susan wasn't feeling well, she went to the store anyway and bought ice cream, pizza, and candy. (Comma after a dependent clause and commas in a list)
- I let my neighbor borrow my phone because she said hers was tapped by the police. (No comma needed here because "because" does not introduce a contrast)
