Explanation
The SI unit of inductance is the henry, represented by the symbol H. It is named after the American scientist Joseph Henry, who discovered self-inductance. One henry is defined as the inductance of a closed circuit in which an electromotive force of one volt is produced when the electric current in the circuit varies uniformly at the rate of one ampere per second. In terms of other SI units, a henry can be expressed as volt-seconds per ampere (V·s/A). While other options like Hertz (Hz) represent frequency and Ohm (Ω) represents resistance, the symbol H specifically denotes the henry in the context of electromagnetic induction.
