To find the sentence that is punctuated correctly, we need to look at the use of commas to set off nonessential information within the sentence.

In the first option, "The oil from Eucalyptus trees which are native, to Australia is known for its medicinal properties," the use of commas to set off "which are native" is incorrect. Nonessential information should be enclosed by commas, but in this case, the sentence is implying that all Eucalyptus trees are native to Australia, which is essential information.

In the third option, "The oil from Eucalyptus trees which are native to Australia is known, for its medicinal properties," the placement of the comma after "known" is incorrect. There should not be a comma separating the verb "is known" from its object "for its medicinal properties."

Therefore, the second option, "The oil from Eucalyptus trees, which are native to Australia, is known for its medicinal properties," is the correct answer. The use of commas to set off "which are native to Australia" correctly indicates that this information is nonessential to the sentence structure while providing additional detail.
