<span>The neighbor waters our plants whom we trust the most while we travel.
The way this sentence is phrased, it sounds as if your trust the plants and not the neighbors.</span>
Declarative if i am not mistaken
Assuming the italicized clause is <em>Since its establishment, </em>the correct answer here is elliptical clause.
Elliptical means that a word which would normally be part of a sentence is excluded, usually for stylistic reasons. Here, the verb is missing, which is why it is elliptical. The question is oddly formulated too - given that there is no verb here, it cannot be a clause, but rather a phrase, but since there is no such option here, then the correct answer is elliptical clause.
