The key factor which fueled competition between European countries for colonies in the Americas was C) the desire to control sources of gold and silver. Although Europe did have certain resources, it had definitely depleted itself in gold and silver and there was a sort of race between the big European super powers to enrich themselves as much as they could. This can be especially seen with the silver mines in Mexico which both the Spanish and the French wanted to acquire.
The correct answer is A) the long growing season.
What allowed the Middle Colonies to develop trade and commerce was the long growing season.
The Middle colonies were New York, New Jersey, Pennsylvania, and Delaware. These territories were blessed with fertile soil -ideal for farming- and long growing season to grow crops. Indeed, they were called "the breadbasket of America" for their good crops such as hemp, wheat, and corn. These colonies traded their crops with other colonies and exported them to Europe.

It would be the development in agricultural knowledge/technology
Development in agriculture enable hunter/gatherer society to shift their behavior. Before this, they had to keep moving from one place to another in order to seek food to live.
After the development in agricultural knowledge/technology, the society now can stay in one exact place for a long period of time and relied on agricultural product as their main source food.
After living in one same place for a long time, the needs to build things to accommodate their living start to arise. They start to built several things and repeat the process every year. In the end, large cities were developed from the initially small hunter/gatherer society.
