Question 15

Physical deterioration results from wear and tear.

Wear and tear refers to the gradual damage that occurs to materials and objects due to regular use and exposure to environmental factors. This process leads to physical deterioration over time, making it the most accurate option among the given choices.

A) Obsolescence

Obsolescence refers to a situation where an object or technology becomes outdated or no longer useful, often due to advancements in technology or changes in consumer preferences. While it can lead to a lack of use, it does not directly involve the physical degradation of items caused by usage.

B) Wear and tear

Wear and tear is the correct answer as it specifically describes the physical deterioration that occurs as a result of regular use. This phenomenon encompasses the gradual breakdown of materials and surfaces due to friction, pressure, and environmental exposure, directly linking it to physical deterioration.

C) Reversion

Reversion typically refers to the process of returning to a previous state or condition, often used in legal or biological contexts. It does not pertain to the physical deterioration of objects and thus is not relevant to the question.

D) Accretion

Accretion involves the gradual accumulation of substances, often leading to an increase in size or mass. This process contrasts with physical deterioration, as it does not entail damage or degradation of materials, making it an incorrect choice in this context.

Conclusion

The concept of wear and tear directly addresses the ongoing physical deterioration that occurs due to regular use and environmental conditions. In contrast, obsolescence, reversion, and accretion do not accurately reflect the processes leading to physical damage, thus reinforcing that wear and tear is the definitive answer.
