Answer:
Since the nature of pollutants is not mentioned in the question, several speculations can be made here.
- Pollutants can affect the photosynthesis: Some pollutants are toxic to plant metabolic reactions such as photosynthesis. This is because of their oxidative nature that can damage the photosystems. This ultimately impairs the plant functioning, e.g. ozone in the air.
- Pollutants can affect the plant-associated microbial communities: Some pollutants such as antibiotics can target plant-associated bacterial communities that are required for plant health. Just like the human gut, plants also have beneficial bacteria that live inside the plant tissues. These bacteria are called endophytes. The harmful nature of the compounds can affect those bacteria which decreases plant fitness.
- Pollutants can compete with nutrients that act as limiting factors: Some pollutants are hydrophobic in nature and make the beneficial nutrients less available to the plants. Likewise, some pollutants reduce the bioavailability of plant necessary nutrients directly. This results in reduced growth and development in plants.
- Pollutants can cause physical damages to plant tissues: Some pollutants are highly reactive in nature and can cause physical damages to the plants. This will result in the attack of pathogens at the wound site which can later take control of host metabolic machinery at later stages. Resultantly, plant fitness is decreased and in some cases, it dies off completely.
It is important to consider that some pollutants are taken up easily by plants whereas other pollutants are difficult. This is because of their water solubility criteria. If a pollutant can be taken up by plant directly, it can cause more damages to the plant as compared to the pollutant which interacts from outside.

Answer:
<h2>Sheep B
</h2>
Explanation:
As given;
Step 1: The nucleus was removed from the egg which was unfertilized and,
which is taken from sheep A, means that the egg was from sheep A.
Step 2 : The nucleus of a body cell which is taken from sheep B was then
inserted into this unfertilized egg which is taken from sheep A. Now the egg contain nucleus of sheep B.
Step 3 : The resulting cell containing nucleus of sheep B was then implanted into the uterus of
sheep C.
Step 4 : finally Sheep C gave birth to a sheep named sheep D.
Sheep B would be most genetically similar to sheep D, because the nucleus was taken from sheep B, and the sheep D is the new born which is formed from the nucleus of sheep B.
