Step-by-step solution
Brassica (mustard) belongs to family Brassicaceae. Family brassicaceae is characterised by polypetalous 4 petals, polysepalous 4 sepals, six stamens (which are in tetradynamous condition i.e. 4 +2 or in two whorls, 4 inner long and 2 outer short). Gynoecium is bicarpellary, syncarpous unilocular with parietal placentation. Fruit is usually siliqua (dry dehiscent fruit formed by bicarpellary syncarpous gynoecium with replum) and rarely lomentum.
