Answer:
B). It breaks down Livingstone's journey into stages and labels them.
Explanation:
Text features are elucidated as the components(headings, captions, sidebars,  bold print, labeling, etc.) apart from the main text that primarily intends to amplify the readers' experiences while reading. 
As per the question, the text features provided in Stewart Ross' 'The Unknown' divides 'Livingstone's journey into different stages' that assists the readers' to understand the information more clearly and effectively while the 'labeling' of these phases helps them in perceiving it cohesively. Thus, these features visually aids and directs the readers to identify and experience the text more impactfully. Therefore, <u>option B</u> is the correct answer.
