The correct answer is: B. Stretcher
A stretcher is a brick laid with its length parallel to the face of a wall. It is the most common type of brick used in masonry construction. Stretchers are typically laid in courses, with each course overlapping the course below it. This creates a strong, stable wall that can withstand the weight of the building above it.
A header is a brick laid with its length perpendicular to the face of a wall. Headers are used to support the weight of the wall
above them, and they are typically laid at regular intervals along the wall. Closers are bricks that are used to fill in the space between the headers and stretchers at the end of a wall.None of these is not the correct answer.
