Question

(A) The shaggy brown dog chased Michael’s cat up into the tree.

Answer 1

I would say that the correct sentence is (D).
answer (C) has the apostrophe in the wrong place, and in (B) the comma doesn't really break up the sentence properly. 'the shaggy brown,' doesn't make sense on its own. and in (A), there isn't any commas at all

Answer 2

It's none of the above and D) has a comma after brown. There's isn't supposed to be a comma there
