Solution
The correct option is B testa and tegmen
Bean seeds have a seed coat with two layers outer testa and inner tegmen. The testa is thick and the tegmen is thin and membranous. Both layers develop from the outer and the inner layers (integuments) of the ovule.
Bean seed or dicot seed have a scar on the seed coat called hilum. This represents the point where developing seeds are attached to the fruit.
Micropyle is a small pore present above the hilum. It helps in the absorption of water at the time of germination.
In monocot seeds, the outer covering of the endosperm is separated by a proteinous layer called aleurone layer.
Coleoptile and coleorhiza are sheaths that enclose the plumule and radicle of the monocot seed, respectively.
