Difference—

Stock is equity, and shareholders enjoy dividends and other profits.

Futures is a contract for buying and selling commodity rights. The holder can make a profit by buying or selling the goods at the original price when the goods are due for physical delivery.

Option, a right contract to buy or sell the subject matter of gambling (stock price, futures price, etc.). ), which can be redeemed at maturity.
