Which of the following statements is true about all issued common stocks?

Common stocks represent ownership in a corporation, and their ownership is typically transferred through organized stock exchanges, such as the NYSE or NASDAQ. Option A is incorrect because common stocks are equity financing, not direct financing (which involves loans or bonds). Option B is incorrect because dividends on common stocks are not fixed; they vary based on company performance and board decisions. Option D is incorrect because common stocks are not secured by tangible assets; they are unsecured equity instruments. This question falls under the Accounting and Finance category, focusing on equity markets.
