Answer:
The correct option is B,decreased total stockholders' equity.
Step-by-step explanation:
Acquisition of treasury shares implies that the company repurchased the shares by retrieving the shares from the shareholders and paying cash in lieu.
When a company repurchased its shares the total stockholders' equity by amount paid in repurchasing the shares.
From an accounting equation perspective, the cash parted with reduces the asset of the company as well as reduces the stockholders' total equity,hence it is a reduction on both sides of the equation.
