Which feature of an Android or iOS mobile device helps prevent malicious programs from infecting the device?​

• The phone carrier prevents the mobile device app from accessing some smartphone features and programs.
• The passcode restricts the mobile device app from access to other programs.
• Mobile device apps are run in a sandbox that isolates them from other resources.
• The remote lock feature prevents malicious programs from infecting the device.
  

  Answers Explanation & Hints: Because mobile device apps do run in a sandbox (an isolated location) it is difficult for malicious programs to infect the device. The passcode and remote lock features secure the device against unauthorized use. The carrier may disable access to some features and programs based on the service contract, but this a commercial, not a security, function.
