The blue-tipped puffer is a migratory bird that is found alo

Option A - INCORRECT.
What we have in question here which is the only animal involved is a bird. This bird is the blue tipped puffer, and the grey fox. So no such thing as small mammal or any other animal seen at the park as at the summer period. And the blue-tipped puffer bird is the prey to the grey fox.

Option B- INCORRECT.
This is never suitable in anyway to the argument or context above. The grey fox that habituated the park much after the bird is in no way close to liking the Thompson's Mulberry tree, rather it's a predator. As a predator, it solely prefers to feed on animals alike rather than any other thing, not even the Thompson's Mulberry tree. This makes it mainly accustomed with places that have other animal.

Option C - INCORRECT.
Trying to measure the speed between the puffer and the fox in this medium is absolutely wrong. The writer never made mention of them running, or most importantly how puffer vacated the park and this shows it was a calculated move which they made in a gradual process. Be that as it maybe, the fox and puffer never engaged on any osrt of marathon as to decide or analyse the speed of any.

Option D - INCORRECT.
This doesn't align with the activities as stated in the question, Thompson's Mulberry tree is the major component seen in the coastal, and the grey fox is never in anyway attracted to the tree or it's fruits. As a predator, grey fox is only attracted to animals, hence, it returned or reintroduced as seen at the park just to prey on the puffer. Moreover it possibly can't extend to the coastal where no puffer or other puffer is.

Option E - CORRECT.
Definitely other coastal areas must have seen the increase or thriving of the blue-tipped buffer over the last decade following the abundant availability of the Thompson's Mulberry tree in the coastal. It is well known that the blue-tipped puffer is a huge lover of the Thompson Mulberry's fruit due to their addiction to the fruit and the safeness of the coastal before the reintroduction of grey fox, one can confidentially state that the puffer have overtime dominated the coastal over the decade.
