The correct option is B Elephant
Rafflesia seeds are dispersed by the feet of elephants. The Rafflesia lives on the exposed roots or vines of other plants. When it dies, the Rafflesia leaves a sticky pulp which contains its seeds. When an elephant steps on it, the pulp sticks to its feet. To wipe it off, the animal rubs its feet against some vine or root. When the seeds reach their suitable habitat, root grows and starts producing the flower.
Therefore, the correct answer is option B.
