I think the answer is B, sorry if I'm wrong and that responded so late after you asked.
Answer: This concept can be used to determine the acceptable level of risk, by placing the amount of risk in a given situation to balance against time, trouble, cost, and physical difficulty of taking precautions to avoid risk. If a balance is seen with risk against this variables, then the risk is acceptable.
The pitfall to applying this concept are as follows;
• it doesn't guarantee safety.
• it is always expensive, if we want to apply this principle to it best.
• it doesn't have a standard order for all kinds of risk. The application varies from risk to risk, also depending on locations of the risk.
Explanation: The ALARP principle is that risk shall be reduced as far as reasonably practicable. This means that zero risk can not be achieved. But we can achieve zero accident, using the ALARP principle.
Before we can boast for achieving ALARP, we must check if the risk is equal or less than time spent,cost, the trouble or challenge, and the physical difficulty of taking a good measure to avoid the risk. If the risk is equal or less than this variables, that means that the risk has been reduced as far as reasonably practicable.
