Correct Answer - B
A seed may have one or two coverings called seed coats. The outer or the only seed coat (if one is present) is called testa while the inner one is named as tegmen. Surface of the seed possesses a fine pore at one end called micropyle. Hilum is a place where funiculus or stalk of seed is borne. Some seeds also show chalaza (place of origin of seeds coats) and raphe (part of funiculus tosed with seed wall).
