Answer:
If this is a grammar question, the answer would be D. It is popular
Explanation:
If you look at the other answers, than you can see which ones do or don't work by putting them into the sentence to see if they work. Ex:
Let's try A, popular it
Since Tampa has a mild winter climate, popular it as a tourist region. Does this one work?
No, it doesn't, so lets try the next answer, B.
Since Tampa has a mild winter climate, that as popular as a tourist resort.
Does this one make sense?
No, this one doesn't work either, so let's try C.
Since Tampa has a mild winter climate, popular as a tourist resort.
This one doesn't make sense either, so we can try the last answer, D.
Since Tampa has a mild winter climate, it is popular as a tourist resort.
This is the only one that works and makes sense, so the correct answer is D.
Hope that helped! :)
