Answer:
C. Two small, plastic balls attached to a larger plastic ball by toothpicks
Explanation:
One molecule of water has 1 oxygen atom and two atoms of hydrogen. Each hydrogen is attached to the oxygen by a simple bond, they share one pair of electron.
Because oxygen is larger than hydrogen, a manner to represent a single molecule is to have two small plastic balls (representing hydrogen) attached to a larger plastic ball (representing oxygen) by toothpicks (representing the bonds), such as the image below.
