ANS:C - battery

In simulation between these two systems, one should know about parameters of at least one system :.

In electrical system:.

Current : nothing but flow of electrons (so some physical quantity).

Voltage: force with which electron is moved from one point to other.

Source: which is the cause for electron movement and voltage production.

So, on comparing with the fluid system we can say that.

Battery = pump.

Fluid=electron i.e. current.

Force I. E voltage/potential = pressure.
