Which process dictates sediment direction around coastal island complexes?

💡 Explanation

Sediment shifts according to prevailing wave directions because longshore drift carries material parallel to the shore, rather than via plate movements or isostatic adjustments in this instance; therefore 'longshore drift' is the correct option.
