Conclusions:

I. All laptops can be roofs → True (only few roofs are laptops)

II. Some Walls is dooms → False (Definite is false)

III. No walls is dooms → False (Definite is false).

As conclusion II and III are complementary pairs so either or case is followed.

Hence, the correct answer is either II or III and conclusion I follow.
