Correct option is B
The correct answer is Altar, as it does not refer to the form and style of megalithic burials. Dolmen, pits, and potholes are forms associated with megalithic burials, but altars are typically linked to ritualistic or religious practices rather than the actual burial style.
Dolmen: Dolmens are large stone structures used in megalithic burials. They consist of upright stones supporting a horizontal capstone, forming a chamber for the deceased. These have been discovered in many parts of the world, including Europe and South Asia.
Pits: Pits were often used as burial sites in megalithic cultures. These pits, sometimes marked with stones or other materials, were dug to bury the deceased. This is a common feature in megalithic burial practices.
Pothole: A pothole is a natural depression in the ground, usually formed by the erosion of rock surfaces. It is sometimes used for burial purposes in megalithic contexts when found in a suitable location, but it is not a style or structure specifically associated with megalithic burials.
Altar: The altar is not directly associated with megalithic burials. Altars were generally used for religious and ceremonial purposes, such as sacrifices or rituals, rather than as burial structures.
