Which invention made mobile phones and tablet devices possible? 1 Decoder 2 Integrated circuitry 3 Microchip 4 Motherboard (I think mother bard but help please)

The correct option is;

Integrated circuit

Explanation:

Following the invention of the transistor, the electrical wiring within an electronic device became known as the major factor contributing to the size of these devices and so in 1958 Jack Kilby and Noyce Fairchild independently developed the Integrated Circuit (IC) model which allowed the integration of the entire circuit onto a piece of solid material, making them smaller, faster, cheaper, more reliable to mass produce, made it possible for the development of smaller computers such as laptops and versions of similar technology, such as mobile phones and tablets due to the ease of standardization of ICs, leading to easier links from design to actual product of small communication devices that rely on ICs.
