@hhhhqqqq, which sentence can't you find? The second one? ("It smells the most delicious"?)
Because I can only interpret that one way... that there is more than one option. For example, there is an apple pie and a cherry pie... "the apple pie smells the most delicious". Sometimes people might omit the "the" in superlative sentences however. For example, "who is (the) fastest?" BUT I would recommend always including the "the" in such cases.
