Higher pitch of the roof i) results in stronger roof ii) results in weaker roof iii) requires more covering material iv) requires less covering material The correct answer is A. (i) and (iii) B. (i) and (iv) C. (ii) and (iii) D. (ii) and (iv)

The correct answer is A. (i) and (iii).

A higher pitch roof is stronger because it has more structural integrity. The steeper the roof, the more weight it can support. However, a higher pitch roof also requires more covering material because it has a larger surface area.

Option (ii) is incorrect because a higher pitch roof is stronger, not weaker.

Option (iii) is correct because a higher pitch roof requires more covering material.

Option (iv) is incorrect because a higher pitch roof requires more covering material, not less.
