The correct answer is D) direct pressure on the wound. The preferred method of controlling external bleeding is to apply direct pressure on the wound using a clean cloth or bandage. This technique helps to slow or stop the bleeding by applying pressure directly to the site of the injury. This is the most effective and safest way to control bleeding, as it does not restrict blood flow to the entire limb like a tourniquet. The other options, while potentially useful in some situations, are not the preferred first-line method. Elevating the wounded area can help, but does not directly address the bleeding. Applying pressure to a pressure point can be effective, but is more difficult to properly execute. Using a tourniquet should be a last resort, as it can cause tissue damage if left on too long.
