Concept:Only companies that are legally allowed to offer ownership interests to the general public can issue shares.
Explanation:Shares represent units of ownership in a company.
When a business issues shares, it sells part of its ownership to investors in exchange for capital.
A public limited liability company is specifically incorporated to raise funds from the public by issuing shares.
Its name often ends with “PLC” and it must publish financial details to protect shareholders.
A partnership is owned by partners, not shareholders, so it cannot issue shares to the public.
A sole proprietorship has only one owner who supplies all the capital, so shares do not exist.
A central bank is a government financial institution, not a commercial business owned by shareholders.
Therefore, the legal business unit that can issue shares is the public limited liability company.
Answer:B. Public limited liability company.
