Final answer:
The situation described is an example of a confined space. This can be highly dangerous and requires immediate action to safely rescue the trapped individual. The correct option is C.
Step-by-step explanation:
The situation described, where a person is trapped in a farm silo, is an example of a confined space. Confined spaces are large enough for a person to enter, but they have limited means of entry and exit and are not designed for continuous occupancy.
In this case, the person is trapped inside the silo, which is a tight and enclosed space. This situation can be highly dangerous as there may be limited ventilation and the person could be at risk of suffocation or exposure to harmful gases.
To resolve the situation, it is important to contact emergency services immediately, as specialized equipment and trained personnel will be required to safely rescue the trapped individual from the confined space. Option C. is the correct one.
