What is the unit of inductance?

The unit of inductance is the Henry. Inductance refers to the property of an electrical conductor or circuit that opposes changes in current. When an electric current flows through a coil or conductor, it creates a magnetic field around it. If the current changes, this magnetic field will induce a voltage that opposes the change in current, a phenomenon known as electromagnetic induction. The Henry is defined as the amount of inductance required to produce one volt of electromotive force when the current changes at a rate of one ampere per second. Therefore, it serves as the standard measure for inductance in electrical engineering and physics.

In contrast, the other units listed serve different purposes: the Ohm measures electrical resistance, the Farad measures capacitance, and the Volt measures electrical potential difference or electromotive force. Each of these units is fundamental in its own context but does not relate to inductance.
