In brick masonry the bond produced by laying alternate headers and stretchers in each course is known as A. English bond B. Double flemish bond C. Zigzag bond D. Single flemish bond

English bond
Double flemish bond
Zigzag bond
Single flemish bond

The correct answer is: A. English bond.

English bond is a type of brick masonry bond in which every other course is laid with headers and stretchers. This creates a pattern of alternating headers and stretchers in each course, with the headers laid perpendicular to the face of the wall and the stretchers laid parallel to the face of the wall.

Double flemish bond is a type of brick masonry bond in which each course is laid with headers and stretchers, with the headers and stretchers alternating in each course. This creates a pattern of headers and stretchers that is staggered from course to course.

Zigzag bond is a type of brick masonry bond in which each course is laid with headers and stretchers, with the headers and stretchers alternating in each course and the headers being laid at a 45-degree angle to the face of the wall. This creates a pattern of headers and stretchers that zigzags from course to course.

Single flemish bond is a type of brick masonry bond in which each course is laid with headers and stretchers, with the headers and stretchers alternating in each course and the headers being laid parallel to the face of the wall. This creates a pattern of headers and stretchers that is similar to English bond, but with the headers being laid parallel to the face of the wall instead of perpendicular to the face of the wall.
