Silica excess --- bricks become brittle and weak.

Alumina excess -- bricks become too hard when burnt and warp on drying and cause cracks.

Lime excess in the form of a lump of lime causes bricks to disintegrate hence bricks shape is lost.

Excess of lime causes the brittleness of brick and the wraping of BRICS is the second effect so the correct answer is alumina.

Lime prevents warping not induced alumina.

So, it is the right answer.
