How is email a useful component of online banking? I. Email alerts can be used to warn you before you overdraw your account. II. You can have your bank statements emailed to you, getting them to you faster. III. Only emailed bank statements can be used to support electronically-filed tax returns.

Email alerts can notify you when your balance is low, helping you avoid overdrawing your account, so I is true. A bank can also email statements, which may arrive sooner than paper statements, so II is true. III is false because emailed statements are not the only records that can support an electronically filed tax return. Therefore, the correct choice is C, “I and II only.”
