The nominal size of the modular brick is A. 190 mm × 90 mm × 80 mm B. 190 mm × 190 mm × 90 mm C. 200 mm × 100 mm × 100 mm D. 200 mm × 200 mm × 100 mm

The correct answer is B. 190 mm × 190 mm × 90 mm.

A modular brick is a type of brick that is used in construction. It is a standard size brick that is used to create a uniform appearance in buildings. The nominal size of a modular brick is 190 mm × 190 mm × 90 mm. This means that the brick is 190 mm long, 190 mm wide, and 90 mm high. The nominal size of a brick is the size that is used in calculations and specifications. The actual size of a brick may vary slightly from the nominal size due to manufacturing tolerances.

Option A is incorrect because the length of the brick is 190 mm, not 90 mm. Option C is incorrect because the width of the brick is 190 mm, not 100 mm. Option D is incorrect because the height of the brick is 90 mm, not 100 mm.
