<u>The correct answer is option (B).
</u>
<u>An investor can earn compounding returns by investing their earnings back into their original investment because when at the same rate of return an additional investment is made then that overall return gets compounded because every penny earned is again invested into the same investment which results in the compounding of returns.
</u>
Further Explanation:
A: By selecting a savings account that has a higher interest rate:
The underlying meaning of compounding of returns is that the earned money is again invested in the same investment with the same rate of return and risk. Although if we take a practical situation, a savings account rarely pays a very high rate of interest on the savings.
Therefore, this option is incorrect.
B: By investing their earnings back into their original investment:
The meaning of compounding return is to reinvest the money earned into the same investment again. Therefore, this option is correct.
C: By transferring their earnings into a high risk investment:
When an individual invests in a riskier investment, there are two conditions which are; either the investor will lose its money; or there will be reward of taking that risk which is profit. But to receive compounding returns from a riskier investment is not possible.
Therefore, this option is incorrect.
D: By diversifying their investment portfolio:
Diversifying a portfolio is the best way to manage your investment as it will help an investor to mitigate its risk and it can also expect greater returns from the investment. Although compounding returns are not guaranteed by diversifying a portfolio.
Therefore, this option is incorrect.
