The correct answer is A.
A financial newspaper provides accurate information about the market prices and movement of stocks. The newspaper is updated daily ( or even more frequently online), so that the information required is always up to date. The financial newspaper is politically neutral, meaning the market information found there is is not biased or influenced by a political party or a particular interest group. The paper may also provide interesting editorials, where some useful tips for investing or the stock market can be found.
TV, colleagues at work, or friends and family can provide useful pieces of information as well but they may not be as knowledgeable on this subject as a specific financial newspaper.
