The correct answer is B. Two directions with break in the slope on each side.
A mansard roof is a type of roof that has four sides, with the lower two sides sloping down at a shallower angle than the upper two sides. The lower sides are often used for living space, while the upper sides are used for attic space. Mansard roofs are often used in European architecture, but they can also be found in other parts of the world.
Option A is incorrect because a mansard roof does not slope in two directions without break in the slope
on each side. The lower two sides of a mansard roof slope down at a shallower angle than the upper two sides.Option C is incorrect because a mansard roof does not slope in four directions without break in the slope on each side. A mansard roof has four sides, but the lower two sides slope down at a shallower angle than the upper two sides.
Option D is incorrect because a mansard roof does not slope in four directions with break in the slope on each side. The lower two sides of a mansard roof slope down at a shallower angle than the upper two sides.
