A)Fabaceae - Legume family
B)Solanaceae - Potato family
C)Liliaceae - Sunflower family
D)Brassicaceae - Mustard family

Answer 1

Hint: The differences in seed, fruit and flower based on their structure have led to segregation of plants into different plant families. One particular family includes only those genera which share similarity in their structures.

Complete answer:
The Liliaceae family is also commonly referred to as the lily family. It is a family of flowering plants that include species of considerable economic importance. They fall in the order Liliales and consist of perennial, monocotyledonous herbs that are often bulbous geophytes whereas the sunflower family which is also referred to as daisy family or the Asteraceae belongs to a different family of flowering plants. It is one of the major families of flowering plants. This family is widely spread. Its flowers are mostly herbaceous which may grow annually or perennially. However, some of its members may be trees, vines or shrubs. It is distributed all over the world ranging from polar to the tropic regions, thus having a diversity of habitats. Therefore Liliaceae - Sunflower family is the incorrect pair.

On the other hand, Fabaceae is also known as the legume family. They consist of pulses and are majorly cultivated for use in human consumption and livestock forage. These crops act as green manure and thus help in enhancing the soil. Moreover, Solanaceae is also known as the potato family which is propagated through tubers. They serve as food and have medical uses also and the family Brassicaceae which is also known as the mustard family is a family of flowering plants. They consist of oil seeds and vegetable crops such as broccoli, cabbage as well.

Hence, the correct answer is option (C)

Note: Asteraceae, also known as compositae family is characterized by composite head having disc florets and a fruit with marginal hairs while liliaceae which is also known as the lily family has solitary flowers with indistinguishable petals and sepals.
