An option buyer is a trader or investor who purchases an option contract by paying a premium to the option seller (writer). In return, the buyer gets the right, but not the obligation, to buy (Call Option) or sell (Put Option) the underlying asset at a specific strike price before or on the expiry date.

You pay ₹500 extra for a flexible ticket (like a premium)
If you travel, you use the ticket
If you cancel, your only loss is ₹500 — no obligation to fly
This is how option buyers operate: risk is limited, potential can be high.
