Answer:
Option A, the liquid level in a capillary tube will drop below the surrounding liquid and the surface in the capillary tube will have a convex meniscus.
Explanation:
A liquid will wet the surface of the container in which it is contained only when the adhesive forces between the molecules of the liquid are weaker than the adhesive force between the surface wall of the container and water.
A convex meniscus is formed when the attractive forces between the molecules of liquid (cohesion) becomes greater than attractive forced between the water molecule and the container's surface (adhesion)
Convex meniscus simultaneously move the surface of the liquid in the downward direction due to which its level become lower than the surrounding layer.
Hence, option A is correct

Answer:
<u><em>The classification is subjected to change due to the increase in scientific knowledge with time.</em></u>
As scientists make novel discoveries, the grouping of organisms changes according to it. For example, at the time of Aristotle, the scientific knowledge was not much advanced. Hence, at that time organisms were simply classified as plants and animals.
With the passage of time, as scientists learn and discover, the scientific classification changes based on these new studies.
