To stagger vertical joints in successive courses of a wall, a piece of brick is generally used at the end of the course, which is known as A. Bat B. Header C. Stretcher D. Closer

Bat
Header
Stretcher
Closer

The correct answer is: A. Bat

A bat is a brick that is cut in half lengthwise. It is used to stagger vertical joints in successive courses of a wall. This helps to distribute the weight of the wall more evenly and prevents cracking.

A header is a brick that is laid across the face of a wall, perpendicular to the stretchers. It is used to support the weight of the wall above it.

A stretcher is a brick that is laid lengthwise in a wall, parallel to the face of the wall. It is the most common type of brick used in masonry construction.

A closer is a brick that is used at the end of a course of bricks. It is cut to fit the space between the last stretcher and the end of the wall.
