The correct answer is option C, that is, behavioral isolation.
The phenomenon of behavioral isolation takes place when two populations possess the tendency of interbreeding, but exhibit distinctions in courtship rituals or other kinds of behavior. For example, the western and eastern meadowlarks are very identical birds whose habitat overlap in the middle of the United States.
However, the members of the two species will not mate with each other, possibly as they use different songs in order to fascinate males. The eastern meadowlarks will not respond to the songs of western meadowlarks, and vice versa.

The structure of the plasma membrane makes this type of transport necessary for fluids is discussed below:
<h3>What do you mean by phospholipid membrane?</h3>
The membrane that divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and is present in all cells. A cell wall is affixed to the plasma membrane on the exterior of bacterial and plant cells.
Because water and other polar or charged substances cannot easily traverse the hydrophobic core of the membrane, the phospholipid bilayer created by these interactions serves as an effective barrier between the interior and exterior of the cell.
