Answer 1

The correct answer is:

(a) Uncoursed rubble masonry

Uncoursed rubble masonry refers to a type of stone masonry where stones of various sizes are used without any regular arrangement or course. The stones are placed in a random manner without any precise alignment, and the joints between them are irregular. This type of masonry is typically used in construction where strength is not the primary concern, such as in retaining walls or foundations.
