Answer:
Es el domingo, 17 de marzo.
Explanation:
When think about what the date says and break it down, you get Sunday to domingo, March to marzo. Remember that some proper nouns in English are not supposed to be capitalized in Spanish unless it is at the beginning of a sentence, such as days, months, and languages. Now let's go ahead and put this into a sentence. Es el domingo, 17 de marzo is the correct sentence here. You can also use the translation method above and combine it with the process of elimination, like I did. I'm not sure if you forgot a period at the end in your question, but if there is a period there, then this will be the correct answer.
Have a great day and I hope I helped!
