Final answer:
The safest method for climbing a tree to enter an elevated stand is using a ladder, which provides stability and reduces the risk of falling compared to other methods like free climbing or using bare hands.
Step-by-step explanation:
The recommended method for climbing a tree to enter an elevated stand is using a ladder. This is because ladders are specifically designed for stability and safety when gaining elevation. Free climbing or using bare hands is not recommended due to the high risk of falling and potential injury. Although ascending with a rope is another method, it typically requires more skill and may not provide the same level of safety as a ladder. Hence, for safety reasons, especially in a hunting context, an appropriately constructed ladder or a manufactured tree stand with a built-in ladder is highly recommended.
