In areas where the walls are frequently washed, conduit should be mounted with a 1/4 inch air space between the wall and the conduit.
Conduits are the structures that are hollow and cylindrical like a pipe, channel or tube through which any material can pass. The material can be electrical wires, gases or even water. Therefore, the functions of conduits is to mediate the transport of materials from one place to another.
These conduits can be rigid or flexible depending upon their use and the material to be transported. Care should be taken when these conduits are embedded inside the wall that they are not very close and in contact with the wall otherwise the conduits may get damaged.

Answer & explanation:
Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.
In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.
In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).
Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.
The answer is the first one because it doesn't create gases and, the third one doesn't even make any sense so its definitely not that one
