The most important ingredient in the brick earth is SILICA. The amount of silica present in brick earth is 50-60% and it prevents cracking and warping of raw bricks.

Alumina is the principal constituent of every kind of brick earth. It imparts plasticity to the brick earth which is essential for proper molding of bricks. Clay in brick earth shrinks and cracks on drying. It also wraps and becomes very hard on burning unless mixed with sand.

Alumina is the right answer. It provides the plasticity to the brick, not the percentage of composition that makes silica the main ingredient.
