The correct answer is C. One Time Password.
An OTP is a unique, one-time password that is sent to the user’s mobile phone or email address for verification purposes. It is used to authenticate the user and prevent fraud.
OTPs are often used in credit card transactions, as they provide an additional layer of security. When a user makes a purchase with their credit card, they may be asked to enter an OTP that is sent to their phone or email address. This OTP must be entered in order to complete the transaction.
OTPs are also used in other online transactions, such as online banking and PayPal payments. They can also be used to log in to websites and apps.
OTPs are a secure way to authenticate users and prevent fraud. They are more secure than traditional passwords, as they are not reused and are only valid for a short period of time.
