Select the correctly punctuated sentence.:

a) Under the tree Angel found three gold coins.

b) Under the tree, Angel found three gold coins.

c) Under the tree, Angel found three, gold coins.

d) Under the tree, Angel found three gold, coins.

The correct answer is B. A cannot be correct because of the inversion, since the prepositional phrase 'under the tree' is at the beginning of the sentence, there has to be a comma after it. And also, there shouldn't be a comma throughout the rest of the sentence. C and D are incorrect because the comma is placed in the wrong spot in both cases.
