Complete Answer:
Compositae or Asteraceae is the largest dicot family among angiosperms. It comprises about 13 subfamilies, over 1900 genera and over 32000 currently accepted species. Compositae is called so because of its characteristic inflorescence, composite type . Examples include sunflower,lettuce,Chrysanthemum, Dahlia and many more.

Additional information:The family is also called Asteraceae because the word master means star in Greek referring to the appearance of some family members as a star surrounded by rays. The petals or sun rays in a sunflower head are actually individually strap-shaped called gray flowers and the sundisk is made of smaller circular shaped individual flowers called disc flowers.

The correct option is B i.e. Compositae.
