Final answer:
The best example of implicit memory is riding a bicycle without consciously thinking about how to do it, which is an action that becomes automatic through practice.
Step-by-step explanation:
The statement that best illustrates implicit memory is C) Riding a bicycle without consciously thinking about how to do it. Implicit memory is a component of long-term memory that is responsible for knowing how to do things, also known as procedural memory. This type of memory allows individuals to perform tasks without conscious awareness of the learned skills needed. An example is how one can ride a bicycle or drive; after repetitive practice, these actions become automatic and can be performed without actively thinking about the necessary motions.
