Final answer:
The Pacific artwork is likely a demonstration of figural representation of humans, a common theme in Pacific art used to convey cultural narratives and roles. The correct answer is option: b. Figural representation of humans.
Step-by-step explanation:
The artwork in question is likely evidence of the trend in Pacific artworks of figural representation of humans. This is because Pacific art, especially in historical contexts, often includes depictions of human figures to convey stories, spiritual beliefs, and societal roles.
While repetition and patterns are also significant elements seen in the artwork, these are usually more decorative or symbolic. Cross-cultural influence may also be present, but without knowing the specifics of the piece in question, such as its historical context or external cultural interactions, it is more challenging to definitively claim cross-cultural influence as the trend represented by the artwork.
