There are important Order of Operations rules which we all need to know and understand.  Some people remember these rules from the acronym PEMDAS.
To be done 1st:  anything within parentheses.

Next, any exponentiation.
Next, any mult. or div.
Last, any add'n or subtr'n.

Please show me which operation you will do first, and explain why.

Yes, it would be D.  Use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction).
Parentheses are ALWAYS what you do first.
