c. (I am assuming that they consider parentheses a form of brackets)

Inner parentheses must be done before outer brackets.
You should to C first, followed by B, A, and then D.

The, simplified, order is Parentheses, Exponents, Multiplication and Division (whichever comes first from left to right) and finally Addition and Subtraction (whichever comes first from left to right).
