The correct answer is: C. Buying and selling securities in the hope of making profit due to change in prices.
Speculation is the buying and selling of assets in the hope of making a profit from changes in their price. It is often associated with high risk, as the value of assets can fluctuate significantly. Speculation can be done on a variety of assets, including stocks, bonds, currencies, and commodities.
Investment is the purchase of assets with the expectation of generating income or capital appreciation. It is generally considered to be a lower-risk activity than speculation, as investors typically hold assets for a longer period of time and are less concerned with short-term fluctuations in price.
Gambling is the activity of betting on an uncertain outcome with the hope of winning money or other stakes. It is generally considered to be a high-risk activity, as there is always the possibility of losing money.
Creating secret profits is the act of making money through dishonest or illegal means. It is often associated with insider trading, which is the buying or selling of securities based on non-public information.
