Answer:
(A) the amount paid for stock reacquired and currently held in treasury, and
(C) a contra-equity account
Explanation:
Treasury stock represents a company's acquisition of its own shares. Thus, in a sense, it means the company will become a part owner of itself, which is frowned at by regulators worldwide. Accordingly, in the computation of stockholder's equity, a company is required to reduce outstanding number of shares by the number of treasury stocks it has acquired (thus representing a contra-equity account due to the deduction).
