Answer:
The correct answer is letter "B": Fran is saving; Miller is investing.
Step-by-step explanation:
In Macroeconomics many points differentiate a saving from an investment. Savings are usually destined for short-term goals, allowing individuals to dispose of that money at any time. Investments are destined to be part of a long-term goal. Money cannot be cashed immediately out of investments since in most cases they are part of a production process, such as machinery in mines, for instance.
In that case, Fran is saving by buying 1000 shares of stock while Miller is investing by purchasing new machinery for one of its breweries.
