Correct Answer: animated

Solution : The second option is the correct answer.

Animated means lively, dynamic, or characterised by motion. In the context of Google celebrating the onset of spring, an animated graphic would likely involve moving images or visual elements to convey the lively and dynamic nature of the season.

The meanings of the other options are as follows:

• Rooting refers to the process of establishing roots, often in the context of plants.
• Freezing refers to the process of turning a liquid into a solid state due to cold temperatures.
• Implanting refers to the action of embedding or inserting something into a surface.

Therefore, the complete sentence is: Google on Saturday celebrated the onset of spring in the northern hemisphere with an animated graphic.
