Answer: Vary, Return, Diversified, Liquidity
Explanation:
Flexible as the name is is something that can change from time to time. So, flexible expenses vary from month to month. They can increase or decrease overtime. So vary is the correct option.
Risk and return increase or decrease together. When risk increases the return on investment must also increase. Also, when risk decreases the return on investment must also decrease.
Diversification refers to the process of spreading up the risk of an investment by investing in less as well as more risky assets in order to spread the risk. When money is divided among different kinds of investments it is diversified.
Liquidity refers to the ease with which money or assets can be converted into cash. Therefore, the ease with which investments convert to cash determines their liquidity.
