Pick up the incorrect statement from the following: A. In Flemish bond, headers and stretchers are laid alternately in the same course B. In Flemish bond every header in each course lies centrally over every stretcher of the underlying course C. In English bond, stretchers are laid in every course D. In English bond, headers and stretchers are laid in alternate courses

In English bond, stretchers are laid in every course, but headers are laid only in every other course. This creates a pattern of alternating stretchers and headers, with the headers laid at right angles to the stretchers.

Flemish bond is similar to English bond, but in Flemish bond, headers and stretchers are laid alternately in the same course. This creates a pattern of headers and stretchers that are laid at right angles to each other, with the headers and stretchers alternating in each course.

The incorrect statement is D, because in English bond, headers are not laid in alternate courses. They are laid only in every other course.
