Although buying a certificate of deposit can earn your higher returns than a regular savings account, it can have the negative side effect of

a. needing frequent transfers to stay active

b. requiring a high initial investment

c. being taxed when invested and when withdrawn

d. having to be tied to a fixed rate saving account

I believe the answer is: b. Requiring a high initial investment

In a certificate of deposit, we store a certain amount of saving in return of interest, but the interest is fixed on a specified rate ( the value would not increase even if the market is doing well)

So, in order to obtain high return on a specified rate interest, you need to put high initial investment.

b is the correct answer
