Solution

The correct option is B Mimosoideae
The compound leaves which are divided twice are called as bipinnate leaves. The leaflets are arranged along the secondary rachis. Each leaflet is called as a pinnule. In Leguminosae, the leaves are stipulate, nearly always alternate, and range from pinnately or palmately compound to simple. The leaves are predominately bipinnate in Mimosoideae (subfamily of Leguminosae). A pair of lateral appendages, present the base of the petiole, are known as stipules. In Mimosodeae, stipules are spiny and hollow inside that provide shelter to ants.
Thus, the correct answer is option C.
