Anoun phrase is a phrase whose central word, the most important word, is a noun.  1 is not a noun phrase because 'the prices will also vary' is not a phrase at all, but rather a clause; 3 is incorrect because 'for the services they provide' is also a clause, although a subordinate one; 4 is incorrect because 'will still be a wide price range' is a verb phrase/this means that there is only one option left, which is number 2 (although i'm not completely sure it is a noun phrase - but if you have to choose one, i'd choose 2).
