Answer:
The correct answer is- C. Pheromones
Explanation:
Pheromones are the chemical signal which are produced by many organisms. Pheromones have some important information which can be understood by the individual of the same species and is used for communication.
Wolfs are lives in pack and they mark their territory with urine and body scent. Thus, when any other wolves enter in an already occupied wolf territory these chemical signals or pheromones give the information to the new wolf that the area is of another wolf.
Therefore here pheromones are most likely responsible for communicating this information to the wolf.

D. temporal
Explanation:
Temporal isolation is a reproductive barrier that occurs when two similar members of a biological population occupying the same habitat breed at different times of the day or at different seasons. When this occurs, the two similar members would be unable to mate with each other. Over time, both individuals become entirely two different species through this evolutionary mechanism
Leaves are green because they contain chlorophyll, an agent that reacts with sunlight and allows plants to undergo photosynthesis, the process that allows plants to make food.
