Which important change in electronic devices, such as televisions and computers, is a result of the use of metalloids as semiconductors?
a) electronic devices have become smaller.
b) electronic devices are now more brittle.
c) electronic devices now use more energy.
d) electronic devices have become more expensive.

Option (A) Electronic devices have become smaller.

Explanation:

Semiconductor devices are the devices which are based on the properties of the  semiconductor materials like  germanium, silicon, gallium and arsenide. The commonly used materials in electronic devices are the silicon and  germanium because of their low cut off voltages i.e 0.7 v and 0.3 v. Semiconductor materials made the electronic devices smaller as they replaced the Vacuum tubes which was bulky with high operating voltage, high power consumption.

it should be all of them because it asks if you included all of those in your answer

explanation:

yes
