When electric current is passed through a conducting solution, there is a change of colour of the solution. This indicates
$(a)$. the chemical effect of current
$(b)$. the heating effect of current
$(c)$. the magnetic effect of current
$(d)$. the lightning effect of current

When the colour of the solution gets changed on passing the electric current through it, it is said to be the chemical effect of an electric current.

Therefore, option $(a)$ is correct.
