The right to choose is a right. An option contract includes at least a buyer and a seller. Depending on the type of option, the holder may have rights or obligations.

As a buyer of options (whether call options or put options), there are only rights but no obligations. His risk is limited (the biggest loss is royalties), but theoretically his profit is unlimited.

As a seller of options (whether call options or put options), he has only obligations and no rights. Theoretically, his risks are infinite, but his income is limited (the biggest income is royalties).
