Well first off, you can easily eliminate choices C and D. They both include the term "quotient" in the choice, and the equation in the question in Multiplication.
Now you can look at the number of factors and terms. There are 2 factors in the equation. And, 2 terms in the parenthesis. The 2 terms in the parenthesis are being added together, so they are looking for the sum of the 2 terms.
So, with this information, we can conclude that A is the appropriate answer choice for this problem.
I hope this answers what you needed!
