Historical Context
Options have a rich history dating back to ancient times, where the earliest forms of options trading can be traced to ancient Greece. Thales of Miletus reportedly used options to secure a low-cost monopoly on olive presses. In the modern era, the development of financial options surged in the 1970s, notably with the establishment of the Chicago Board Options Exchange (CBOE) in 1973, which standardized options contracts and improved their accessibility.

Detailed Explanation
Options are contracts between two parties: the buyer (holder) and the seller (writer). The buyer pays a premium to gain the right, but not the obligation, to buy or sell an asset at a predetermined price within a specified timeframe. This non-obligatory feature differentiates options from futures contracts, which require both parties to fulfill the contract terms.
Pricing Models
The most famous model used for option pricing is the Black-Scholes Model, given by:
Where:
- \( C \) is the call option price.
- \( S_0 \) is the current stock price.
- \( X \) is the strike price.
- \( r \) is the risk-free interest rate.
- \( t \) is the time until maturity.
- \( N(\cdot) \) is the cumulative distribution function of the standard normal distribution.
- \( d_1 \) and \( d_2 \) are calculated as follows:
