Answer 1

The correct option is C Hypogynous flowers

Asteraceae or Compositae, commonly known as sunflower family is an economically important family of flowering plants. In Asteraceae, cypsela fruit is present. Cypsela is a dry single-seeded fruit formed from a double ovary, of which only one develops into a seed, Capitulum inflorescence is seen which consisting of a few or a large number of flowers or florets closely arranged on an axis surrounded by involucral bracts. Epigynous flowers (stamens and other floral parts are situated above the ovary). Stamens are 5, syngenesious (filaments are free and anthers are united) anthers are present. Calyx is poorly developed which is modified into pappus.

So, the correct answer is 'Hypogynous flowers'.
