Answer:
Option C
Dr. Treasury Stock 67,200
Cr. Cash 67200
Explanation:
Before March 4, 2019
The reason is that when the stock was issued the entry was:
Dr Cash $67200
Cr Common Stock $67200 ... 2100 * $32 per share
On March 4, 2019
So if the 1600 out of 2100 are repurchased then the above entry would be reversed but here their is a small difference which is that the term common stock would not be used and instead we will use Treasury Stock because this is the term that is used when the common stock is decreased by repurchase of shares.
Dr Treasury Stock $67,200
Cr Cash $67,200
So the right answer is option D.
