Final answer:
The literary device primarily used in the student's poem is simile, characterized by comparisons using 'like' or 'as', though imagery and repetition are also present. The correct answer to the question is d) Repetition.
Step-by-step explanation:
In the poem provided by the student, the literary device prominently used is simile. A simile is a figure of speech that compares two different things in an interesting way, often connected by words 'like' or 'as'. For example, in the line 'thoughts ricochet, Like a tornado in the wind', the poet uses 'like' to compare the chaotic movement of thoughts to a tornado.
The use of imagery is also evident in the poem, as the poet uses descriptive language to create visual pictures in the reader's mind, such as 'ocean rushed in' and 'never ending road'. Finally, repetition is featured in the recurring phrase 'over and over', which emphasizes the continual nature of the subject's experience.
Based on these observations, the correct answer to the student's question would be d) Repetition, though similes and imagery are also used as literary devices within the poem.
