Which of the following best explains why a small, dense object, such as a metal needle, can float on the surface of water despite being denser than water?

The needle creates a vacuum underneath it, reducing the buoyant force.

The surface tension of the water creates a force that counteracts the weight of the needle.

The needle displaces a volume of water equal to its weight, allowing it to float.

The temperature of the water increases the buoyancy of the needle.
