Final answer:

The statement 'animals which constantly stretch their necks will grow longer necks' is NOT a theory about how change occurs in species.

Step-by-step explanation:

The statement animals which constantly stretch their necks will grow longer necks is NOT a theory about how change occurs in species. This statement implies that individual organisms can intentionally change their own characteristics, which is not supported by scientific evidence. Evolutionary change occurs through the process of natural selection acting on genetic variation within a population, not through individual actions.

Answer:

The correct answer is "Change happens in a slow, steady way".

Step-by-step explanation:

The missing options of this question are:

A. Change happens in quick bursts.

B. Change happens in a slow, steady way.

C. Change happens only when a species becomes extinct.

The correct answer is option B. "Change happens in a slow, steady way".

The statement of "Change happens in quick bursts" is part of the punctuated equilibrium theory, which states that quick speciation events happen upon the presence of drastic environmental events. The statement of "Change happens only when a species becomes extinct" is part of a theory that states that before a species faces dramatical physical changes, other species must become extinction. On the other hand the statement of "Change happens in a slow, steady way" is not formally part of any theory.
