Antibodies have a variable region that binds to a specific antigenic determinant.

Antibody

An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses. The antibody recognizes a unique molecule of the pathogen, called an antigen. Each tip of the "Y" of an antibody contains a paratope (analogous to a lock) that is specific for one particular epitope (analogous to a key) on an antigen, allowing these two structures to bind together with precision. Using this binding mechanism, an antibody can tag a microbe or an infected cell for attack by other parts of the immune system or can neutralize it directly (for example, by blocking a part of a virus that is essential for its invasion).

Answer:

Rain makes up part of earth's water cycle

Water evaporates from streams, lakes, and oceans, then condensation and precipitation occur in the form of rain.

Explanation:

I'm pretty sure this question is implying that the answers should be directly related to the water cycle. While some of the other sentences might have some truth to them, they are too vague to be considered fact, and they're not necessarily related to the process of the water cycle.
