Each of the options represents a unique aspect of Polynesian art and culture. However, if one were to choose the work that best represents Polynesian art as a whole, Easter Island Heads (Moai) would be a strong contender.
These monumental statues are iconic symbols of Easter Island (Rapa Nui) and reflect the culture, spirituality, and craftsmanship of the Polynesian people. While stick charts and Lapita pottery also have significant cultural value and represent specific regional art forms, the Moai have gained international recognition and are often considered a symbol of Polynesian heritage.
So, the best representative work among the options might be Easter Island Heads.
