{'fuse wire': [0, 0, 0, 1], 'electric current': [0, 1, 0, 6], 'magnetic effect': [0, 0, 0, 2], 'optical property': [0, 0, 0, 1], 'heating effect': [0, 0, 0, 3], 'chemical effect': [0, 0, 0, 2], 'property': [15, 0, 8, 22]}

The correct answer is option 3: heating effect of current.

When an electric current passes through a conducting material, it generates heat. This phenomenon is known as the heating effect of current. In the case of a fuse wire, it is designed to have a relatively low melting point.

When a high amount of current passes through the fuse wire, due to a short circuit or overload, the heating effect of the current causes the temperature of the wire to rise. Eventually, the temperature reaches the melting point of the wire, leading to the wire melting and breaking the circuit.

The chemical effect of current (option 1) refers to the ability of electric current to cause certain chemical reactions, such as electrolysis, but it is not applicable in the case of a fuse wire.

The magnetic effect of current (option 2) refers to the creation of a magnetic field around a current-carrying wire. This effect is not directly applicable to the function of a fuse wire.

The optical property of current (option 4) is not a valid concept.

Therefore, the heating effect of current is the most applicable property in the function of a fuse wire.
