C. There were many harbors and abundant timber.
Step-by-step explanation:
Shipbuilding developed in the New England colonies because there were many harbors and abundant timber.
Since the climate in New England was cold and the soil wasn't very fertile, it was hard to grow crops or focus on agriculture for a living. Thankfully, the New England colonies had other ways of making money.
New England had a lot of areas full of woods, meaning there was an abundance of timber. This meant that it was easy to build things like ships, homes, and furniture. There were also many harbors, as New England was a hot spot for merchants and slave trading. Ships were created not only for these two reasons but also for fishing.
