Final answer:
The knowledge of at which temperature water boils is an example of C. crystallized intelligence.
Step-by-step explanation:
Crystallized intelligence is characterized by acquired knowledge and the ability to retrieve it. When you learn, remember, and recall information, you are using crystallized intelligence. In this case, knowing the boiling point of water (100°C) is a learned fact that can be retrieved when needed.
On the other hand, fluid intelligence encompasses the ability to see complex relationships and solve problems. It involves thinking outside the box and tackling abstract challenges. Navigating your way home after being detoured onto an unfamiliar route due to road construction would draw upon your fluid intelligence, as it requires problem-solving and adapting to the situation.
In conclusion, the knowledge of the boiling point of water is an example of crystallized intelligence, as it involves acquired knowledge that can be recalled. It is not an example of fluid intelligence, which focuses on problem-solving and complex relationships. The correct answer is C. crystallized intelligence.
