Karen doesn’t like driving to the local bank branch, but doesn’t think that it is secure to do financial transactions on her phone. What is the best banking option for her?

Based on Karen's situation, since she doesn't like to pay a visit to the local bank branch, nor do financial transactions through her phone because of security purposes, the best banking option for her would only be TELEPHONE BANKING. In telephone banking, you have the option to do transactions by making calls.
