Options contracts can be broadly classified into the following types:

1. Call Options: A call option gives the buyer the right but not the obligation to buy an underlying asset at a predetermined price (strike price) within a specified time period. The seller of the call option is obligated to sell the asset if the buyer exercises the option.

2. Put Options: A put option provides the buyer the right but not the obligation to sell an underlying asset at a predetermined strike price within a specified time period. The seller of the put option is obligated to buy the asset if the buyer exercises the option.

3. American Options: American options can be exercised at any time before the expiration date. This flexibility makes them more valuable compared to European options, where exercise is only possible at expiration.

4. European Options: European options can only be exercised at expiration. The buyer has to wait until the expiration date to exercise the option.

5. Asian Options: Asian options\' payoff is determined by the average price of the underlying asset over a specific period. This average price is compared to the strike price to determine the option\'s value.

6. Bermuda Options: Bermuda options have specific dates before expiration when exercise is allowed. These options offer a middle ground between American and European options.

7. Barrier Options: Barrier options have a specific price level (barrier) that, if breached, can change the option\'s characteristics. It can either activate or deactivate the option, depending on whether it is a knock-in or knock-out option.

8. Binary Options: Binary options have a fixed payout if the option expires in the money, or no payout if it expires out of the money. They are often used for speculative purposes.

9. Exotic Options: Exotic options have unique features that differentiate them from standard options. These can include options with complex payoffs, options on multiple assets, or options with non-standard exercise conditions.

10. Employee Stock Options (ESOs): ESOs are granted by a company to its employees, providing them with the right to buy company shares at a predetermined price within a specific period. These options are often used as part of employee compensation packages.

It is important to note that the classification of options contracts may vary slightly depending on the context or specific industry.
