D) All of these.

The amount of heat produced in a wire depends on multiple factors, including the material, length, and thickness of the wire.

Material: Different materials have different electrical resistivities, which affect the wire's ability to conduct electricity. When an electric current flows through a wire, the resistance of the wire causes it to heat up. Materials with higher resistivity tend to produce more heat for a given current, while materials with lower resistivity generate less heat.

Length: The length of the wire affects its resistance. Longer wires have higher resistance compared to shorter wires of the same material and thickness. As the resistance increases, more heat is generated when a current passes through the wire.

Thickness: The thickness, or cross-sectional area, of the wire also affects its resistance. Thicker wires have lower resistance compared to thinner wires of the same material and length. With lower resistance, less heat is produced when the wire carries a given current.

Therefore, all of these factors (material, length, and thickness) influence the amount of heat produced in a wire.
