I believe that the correct option is: D) colons.
Extended quotations that are longer than three lines are introduced with a colon and then they start on a new line but having its entirety indented half an inch from the left margin.
For example:
Mary begins to talk about her past:
(this is where the quotation is)
<span>The
territories (the Arctic), rural areas especially in the prairie
provinces. Access to transportation would be the best in cities,
especially cities in Southern Ontario, Southern Quebec, some maritime
provinces as well as the Vancouver area of BC.</span>
Can you be a little more specific
"the process of receiving or giving systematic instruction, especially at a school or university:"
Him.
If you don't know how to solve this, you can put each word in to the blank and see which sounds right.
