Answer:
d. none/decrease
Step-by-step explanation:
There is no impact in Total Paid-in Capital account because if the shares are repurchased and keeped in Treasury stock the entry is as follows:
Treasury Stock - DEBIT
Cash - CREDIT
The Treasury account it's reported on the balance sheet statement under the stockholder's equity section as a contra- equity accounts that means that the balance of this account decreases the total value of this section.
If the company decides to retire the share of the market, then it's necessary to deduct it of Common Stock and Paid in Capital account and the Treasury account will have zero balance in the balance sheet.
