Answer: A
Step-by-step explanation: though they did phrase it in a very weird way, and I would suggest to you to make sure your formatting of your question is understandable, A demonstrates distributive property. you can imagine this as two little arrows going from the multiplier outside the parentheses, to each number inside them. this property is used a Lot in basic algebra and using variables. basically, instead of adding inside the parentheses first, and then multiplying that answer by the outside number, you just multiply the outside number by each number inside the parentheses Individually. and then follow through with the operation. this can get confusing if subtraction or negatives are involved, but I'm sure you'll figure it out :)
