(C) During microsporogenesis,the microspore mother cells $(MMC)$ undergo meiosis to form a cluster of four cells known as the microspore tetrad. These four cells are held together by a callose wall. The $Tapetum$,which is the innermost layer of the microsporangium wall,secretes the enzyme callase. This enzyme breaks down the callose wall,allowing the four microspores to separate and develop into pollen grains.

The enzyme callase,which degrades the callose wall of the microspore tetrad to release four microspores,is provided by the:
