The correct ascending order arrangement in terms of size and space requirement is as follows:

Vacuum Tube (largest and requires the most space)
Transistor (smaller and more compact than vacuum tubes)
Integrated Circuit (smallest and most space-efficient)
So, Option B is the correct arrangement.

Ascending Order Arrangement in Terms of Size and Space Requirement:

To determine the correct ascending order arrangement in terms of size and space requirement between vacuum tubes and integrated circuits, we need to compare the characteristics of both technologies.

Vacuum Tubes:
1. Vacuum tubes are electronic devices that control the flow of electric current through a vacuum.
2. They were widely used in early electronic systems, including computers and radios.
3. Vacuum tubes are relatively large in size and require more physical space compared to integrated circuits.
4. They consist of a glass or metal envelope containing electrodes, which emit and control the flow of electrons.
5. Due to their larger size, vacuum tubes also consume more power and generate more heat.

Integrated Circuits:
1. Integrated circuits (ICs) are miniature electronic circuits consisting of multiple electronic components, such as transistors, resistors, and capacitors, fabricated on a single semiconductor material.
2. They revolutionized the field of electronics by enabling the miniaturization of electronic devices.
3. Integrated circuits are significantly smaller in size compared to vacuum tubes.
4. They require less physical space, allowing for the development of smaller and more compact electronic devices.
5. Integrated circuits also consume less power and generate less heat compared to vacuum tubes.
6. They have higher reliability and durability due to the absence of moving parts.

Correct Ascending Order:
Based on the above characteristics, the correct ascending order arrangement in terms of size and space requirement is as follows:

1. Vacuum Tube
2. Integrated Circuit

This means that vacuum tubes are larger in size and require more physical space compared to integrated circuits. Integrated circuits, on the other hand, are significantly smaller and more compact, making them suitable for modern electronic devices that require miniaturization and portability.

Conclusion:
Integrated circuits have revolutionized the field of electronics by providing smaller size, lower power consumption, higher reliability, and greater efficiency compared to vacuum tubes. This has led to the widespread adoption of integrated circuits in various electronic devices, including computers, smartphones, and other consumer electronics.
