Answer:
The false statement is letter "C": A stock buyback refers to the purchase of the firm's shares of stock by the firm's debt holders.
Explanation:
A stock buyback refers to publicly traded companies buying back their shares from shareholders -not debt holders as in option "C". This reduces the number of outstanding shares in the market and typically in simple market dynamics raises the stock price. Companies fund their buybacks with excess cash. since they do not find any other better destination for that money.
