Which online service is primarily used for managing bank accounts?

Internet Banking is the correct choice because it encompasses a wide range of online services that allow individuals to manage their bank accounts efficiently. Through Internet Banking, users can perform transactions such as checking account balances, transferring funds, paying bills, and setting up direct deposits, all from the comfort of their computers or mobile devices.

Mobile Banking, while also relevant, specifically refers to banking services conducted via smartphones, which is a subset of Internet Banking. Digital wallets are primarily used for storing payment information and making payments, but they do not typically offer the full suite of banking services available through Internet Banking. Online savings often refers to savings accounts that can be accessed online but doesn't explicitly cover the full management capabilities of bank accounts provided by Internet Banking. Thus, Internet Banking is the most comprehensive choice for managing various banking activities online.
