Hi Sergio

The test question has nothing to do with the present perfect. 'Have to' has a meaning similar to 'must' in the test sentence. However, you cannot say "will must". So, if you wanted to use 'must' instead of 'have to' in the sentence, then you could only write this:
"I must hurry."

If you want information about the difference between the present perfect simple and the present perfect continuous, please post a separate question in the forum called "English Grammar, Vocabulary and Idioms":
