The selection of the appropriate punctuation for the sentence hinges on how the phrase referring to the figure is integrated into the larger context of the sentence. In this case, the best approach is to treat the reference to "figure 1" as supplementary information that clarifies or supports the preceding statement regarding the increase in the length of utterances.

The correct choice incorporates parentheses while maintaining the clarity of the overall sentence. This grammar structure effectively separates the main idea from the additional information about the figure, creating a cohesive yet nuanced statement. The use of parentheses indicates that the reference to the figure is related but not essential to the main sentence. This keeps the original statement intact and clear, providing a clean break for readers to understand the main point while also directing them to further supporting details.

Using the phrase in such a manner allows for seamless reading where "See figure 1" acts as a cue for additional reference without disrupting the flow of the primary assertion about the developmental stages. Additionally, this construction maintains the standard academic convention of referencing figures, ensuring that the text adheres to formatting guidelines often found in research papers.
