Which type of financial instrument obligates the buyer to purchase an asset at a predetermined price on a specified date?

Bonds are debt instruments that represent a loan made by an investor to a borrower, typically corporate or governmental. While they provide periodic interest payments and return principal at maturity, they do not obligate the buyer to purchase an asset at a set price on a future date. Instead, bonds are fixed-income securities and represent a form of investment rather than a purchase obligation.

Options are financial derivatives that give the buyer the right, but not the obligation, to purchase (call option) or sell (put option) an asset at a predetermined price before or at a specified expiration date. This key characteristic differentiates options from futures, as options do not create a binding obligation to buy or sell the underlying asset.

Stocks represent ownership shares in a company and do not involve any obligation to purchase assets at predetermined prices. Investors buy stocks to gain equity in a company and may benefit from dividends and capital appreciation, but they are free to buy or sell shares at their discretion rather than being bound by a contract.
