Answer
Causing a build-up of TAR
Explanation
Smoking indeed does affect the lungs, but not all options provided are entirely accurate regarding how it reduces the surface area of the lungs. Regular and heavy smoking can cause damage to lung tissue and disrupt the function of the lungs. Let's break down each option :1. Causing an addiction to nicotine: Although nicotine, a major source of addiction to cigarettes, plays a serious role in smoking addiction and can have various negative health impacts, it does not reduce the lung surface area.2. Blocking arteries with fat deposits: This primarily results in cardiovascular disease, rather than effecting a decrease in lung surface area.3. Causing a build-up of tar: Among the options offered, this is the most direct and significant impact caused by smoking. Tar deposits from smoking directly damage the alveoli (small sacs) and bronchioles (small air ways) in the lungs, reducing their effective surface area for gas exchange, promoting diseases like COPD and Emphysema. Hence, 'the building up of tar' most appropriately belongs to the mechanism smoking utilizes to reduce surface area in the lungs, although 'ALL of these' is technically incorrect for the given reasons.
