Solution

The correct option is C a router

The purpose of vacuum tube was to NOT act like a router.

A vacuum tube (also called a VT, electron tube or, in the UK, a valve ) is a device sometimes used to amplify electronic signals. In most applications, the vacuum tube is obsolete, having been replaced decades ago by the bipolar transistor and, more recently, by the field-effect transistor .

High power consumption; needs heater supply that generates waste heat and yields lower efficiency, notably for small-signal circuits. Glass tubes are fragile, compared to metal transistors. Sometimes more prone to microphonics than transistors, depending upon circuit and device.

The vacuum tube is a glass tube that has its gas removed, creating a vacuum. Vacuum tubes contain electrodes for controlling electron flow and were used in early computers as a switch or an amplifier. ... Today, vacuum tubes are no longer used in electronic equipment.
