Final answer:
David's action of giving out candies is an example of the Distributive Property, where multiplication is distributed over addition. So the correct answer is option D.
Step-by-step explanation:
The scenario where David gives Charlotte and Grace a bubblegum and a chocolate each, represented as 2(bubblegum + chocolate) = 2*bubblegum + 2*chocolate, illustrates the Distributive Property. This property states that multiplying a number by a sum is the same as doing each multiplication separately. In this case, David is distributing 2 candies each of both types to two people, effectively giving 2 bubblegums and 2 chocolates.
