(Volt. sec)/Ampere is the unit of:

Correct option is B

​$$\text{The unit of inductance is the Henry (H). It can be expressed in terms of other units as follows:} \\1\, \text{Henry} = \frac{\text{Volt} \cdot \text{second}}{\text{Ampere}} \\\text{This is derived from the relationship between the induced electromotive force (emf), inductance, and the rate of change of current:} \\V = L \frac{dI}{dt} \\\text{where:} \\\bullet \quad V \text{ is the voltage in volts,} \\\bullet \quad L \text{ is the inductance in henries,} \\\bullet \quad \frac{dI}{dt} \text{ is the rate of change of current in amperes per second.} \\\text{Thus, the unit } \frac{\text{Volt} \cdot \text{sec}}{\text{Ampere}} \text{ corresponds to inductance.} \\\text{Therefore, the correct answer is (b) Inductance.}$$​​
