$A$ graph of magnetic flux $\phi$ versus current $(I)$ is shown for four inductors $A, B, C, D$. The inductor with the smallest value of self-inductance is:

When a wave traverses a medium,the displacement of a particle located at $x$ at a time $t$ is given by $y = a \sin (bt - cx)$,where $a, b,$ and $c$ are constants of the wave. Which of the following is a quantity with dimensions?
