Check the options given for most correct answer:(i) is dispersed by wind. So it should be very light in weight. Correct answer could be Maple (Option A) or Milkweed (Option B). Both are very light.Next, Coconut and Lotus are dispersed by X. Both of these grow very near to water. So, they will be dispersed by water. That means X is Water. So, Option A and Option C could be the right answer.But Option A is common in both. So, let’s confirm by checking the right option for (ii) and Y.Seeds dispersed by Animals will be Mango and (ii). Cocklebur are the seeds of Xanthium. They are hard and have stiff, pointed thorns/spines. So, these attach to the animals’ hides and taken away. So, (ii) is Cocklebur.Peas and Poppy seeds are dispersed when the fruits split and burst open. So, Y is Explosion.That means Option A is the correct answer
