(B) “Production and demand decreased with increased oil usage”
This was one of the factors for the decrease in demand for coal.
<u>Explanation:</u>
In 1930s, during the Great Depression period, the market saw a massive decline in the production of coal and a small steady increase in that of oil.

Cost of mining and producing coal was very high. Lower prices and increased production of oil helped the producers to gain profit. This is one of the factors that helped oil to succeed ahead of coal.

Colonial Governments
Each of the thirteen colonies had a charter, or written agreement between the colony and the king of England or Parliament. CHARTERS of royal colonies provided for direct rule by the king. A COLONIAL LEGISLATURE was elected by property holding males. But governors were appointed by the king and had almost complete authority — in theory. The legislatures controlled the salary of the governor and often used this influence to keep the governors in line with colonial wishes. The first colonial legislature was the VIRGINIA HOUSE OF BURGESSES, established in 1619.
