Available Options are:
Option A. Start making "opportunity cost' decisions now! Start giving up something nice now for something a lot better later.
Option B. When you get your first credit card, do not use that credit card to regularly finance any purchases!
Option C. Never invest more than you can afford to lose.
Option D. All of the above.
Answer:
Option D. All of the above.
Step-by-step explanation:
The reason is that determining whether the investment is the best option by using the opportunity costing technique helps in identifying the best option.
Using credit card rarely decreases the interest which means that the good investor must increase its savings.
The third option talks about the risk that an investor must bear associated with an investment. An investor must not bear more than the level which is harmful for him. Again this is sign of smart steps that every investor must consider.
So all the options are correct.
