(C) Mustard
(D) Cucurbita

Answer 1

Hint: The fruit dispersal is the very important process in which the Seeds contained inside fruits should be scattered a long way from the mother plant, so they may discover ideal and less serious conditions in which to sprout and develop into a plant.

Complete Answer:
- Xanthium are bristly and possess hooks in the seeds that may stick to the fur or the hairs of the animals and get scattered distant spots.
- They additionally get scattered by wind. At the point when climatic conditions are great, they burst open by the explosive mechanism and are moved distant places and sprout into new plants.
- The fruits of Xanthium are transmitted by the animals like goats and cows, when these animals are benefiting from their leaves, these seeds get appended to them.
- Sunflower seeds scatter through the activities of individuals and animals just as wind and water. Some plants scatter the seed by the explosive mechanisms.
- A portion of the plants that scatter their seeds as such incorporate plants of the pea, mustard and amber family. The fruits that are transmitted by the mammal are bigger, sweet-smelling and not brilliant and typically have bigger seeds than winged animal organic products

Thus, the option (B) is correct.

Note: When the plants themselves complete the dispersal, the cycle is called dehiscence. In dehiscence or scattering by blast, a seed-containing structure. For example, blasts shooting the seeds into the air. These seeds land up away from the parent plant.
