A current-controlled, three-terminal semiconductor device used for the control and amplification of electronic circuitry is called transistor
A transistor is a semiconductor device that switches or amplifies electrical impulses. The transistor is one of the fundamental components of contemporary electronics. [1] It has at least three terminals for connecting to an electronic circuit and is made of semiconductor material. The current flowing through another pair of the transistor's terminals is controlled by the voltage or current provided to one set of those terminals. Because the regulated (output) power might be higher than the controlling (input) power, a transistor can amplify a signal. Although many more transistors are found embedded in integrated circuits, some are packaged individually.

Answer: C. The economy is characterized by dynamic change and imperfection.
Explanation: The natural rate of unemployment can be explained as the limit on the lowest or minimum level of unemployment a nation can achieve from standard resources or output. It has often been argued that even in healthy economies the natural rate of unemployment cannot be zero due to factors such as flexibility, technological replacement and some who lack the required skill to be employed, imperfect information. Flexibility or dynamic nature of the market affords individuals the opportunity to change or swap jobs, fresh graduate who may need a bit of time to find jobs, recession characterize the dynamic nature of the economy, imperfection in information in capital and labor market is also a contributing factor.

The correct answer is formal reasoning
Explanation:
Thought frees itself from direct experience and the child's cognitive structures mature. This means that the potential quality of their thinking or reasoning reaches its maximum when formal operations are fully developed. Presents the hypothetical-deductive reasoning.
