Explanation:

Reese buys securities and after 8 months when the prices go up, she sells the securities in a higher amount. There is difference of $400 in these prices. This difference is called the spread.

Spread is basically difference in the price of the same good at different dates. The securities Reese bought are sold 8 months later. So, it is the spread, Option D.
