What does mobile banking mean?

Correct answer: Using banking services through a mobile phone

The direct answer is A: using banking services through a mobile phone. Mobile banking means carrying out banking activities with a mobile phone, usually through a bank app, mobile website, or secure phone service. A customer may check balance, transfer money, pay bills, or receive account information without going to the branch. Option A is correct because it gives the meaning directly. Option B, only visiting a bank building, describes branch banking and uses the opposite idea; mobile banking is meant to reduce the need for a physical visit. Option C, hiding cash, is not a banking service and has no connection with digital transactions. Option D, opening a bank in a field, describes a location and not a mobile method of using banking services. The reasoning chain is: mobile phone plus digital banking facility equals mobile banking. The exam cue is to notice words such as phone, app, online transfer, or mobile payment. A common mistake is thinking that mobile banking means a bank building or a mobile bank vehicle; it means banking through the phone.
