Answer: C. A decrease to assets for $45,000.
Step-by-step explanation:
When shareholders redeem their stock, the company pays them for the redeemed stock at a certain price which in this case is $45.
The total cost of redemption is therefore:
= 45 * 1,000
= $45,000
The company uses cash to pay for this which is an asset. Assets will therefore reduce by $45,000 which is the amount of cash paid.
