Which of the following components is included in cardholder data?

Cardholder data consists of specific information related to payment card transactions, particularly data that can be used to identify an individual cardholder in conjunction with a payment card. The expiration date is a crucial part of the cardholder information as it is directly associated with the payment card itself and is essential for processing transactions.

This component helps validate the card's legitimacy and is required to complete a transaction, making it a key piece of cardholder data that must be protected according to PCI DSS requirements. In contrast, elements like a credit score, social security number, and home address do not make up the cardholder data as defined by PCI DSS, focusing instead on directly transaction-related information.
