Which item would be considered a complementary good for a kayak?

Question

Quizplus · Accepted Answer

A life jacket is a complementary good for a kayak because it is a necessary safety item that enhances the experience of using a kayak. While a canoe and jet ski are similar items that could be used instead of a kayak, they are not complementary goods as they are substitutes. Good weather is not an item, but rather a condition that does not directly enhance the experience of using a kayak, making it also not a complementary good.
