The sum of the three major components (operating, investing and financing activities) on a statement of cash flows will add up to:?

Yes - Option B is the right answer.

B------------------------------------------

b. the change in the cash account balance between the beginning and ending of the period. 

Option B is correct...........

option b============================

There is no option provided in the question. The answer should be added to the beginning cash balance. The need for the cash flow is to show where the investors cash has gone ( when the ending is lower than the beginning) or from where it comes( the reverse).

Operating + Investing + Financing = NCF. This NCF can be positive or negative and this is added to the beginning of the cash and arrived at the end of the cash balance.

A-Cannot be the answer b/s it will be added to beginning cash balance

B- NCF = the change b/n beg. and Ending cash. It will be counting twice

C - Is the same as B

D- Net Income has already be considered when calculating Operating Income. no need to do that twice

My Answer would be option E

E - added to the beginning balance

c. the amount of cash inflow for the period.

My answer is letter (C). It will add up to "Amount of cash inflow for the period". Or the Beginning Cash Balance to arrive at the Ending Cash Balance when added. 

answer b is correct answer "the change in the cash account balance between the beginning and ending of the period.".....
