The correct answer is A. Perform a factory reset, because the symptoms strongly indicate a serious mobile malware infection, potentially including spyware or a trojan installed from an unofficial app store. Random pop-ups, excessive data usage, blocked access to banking apps, and inability to update the OS are classic indicators that malicious software has gained deep system-level access.

According to the Quentin Docter -- CompTIA A+ Complete Study Guide, mobile malware installed from unofficial sources can embed itself deeply into the operating system, sometimes gaining device administrator privileges. In such cases, standard remediation steps such as clearing cache or uninstalling apps may be ineffective.

The Travis Everett & Andrew Hutz -- All-in-One Exam Guide explains that when a mobile device shows signs of persistent compromise---especially when core OS functions and security-sensitive applications are affected---the recommended first step is to perform a factory reset. This completely wipes user-installed applications and restores the device to a known-good state.

The Mike Meyers / Mark Soper Lab Manual reinforces that changing passwords is important after the device is secured, not before. Contacting support or clearing cache does not remove deeply embedded malware.

Therefore, to immediately address the security threat and regain control of the device, a factory reset is the most appropriate first action, making A the correct answer.

Linux distributions are open-source and generally free of licensing fees, making them suitable for both desktop workstations and servers. Organizations can use the same Linux OS across all their systems without incurring per-seat or per-server costs, unlike proprietary systems such as Windows or macOS.

A very large or complex spreadsheet can consume excessive RAM and CPU cycles, causing the application to hang or become unresponsive. By checking the file's size and monitoring how much memory Excel (or the spreadsheet program) uses when opening it, the technician can confirm whether resource exhaustion is the culprit and take steps - like simplifying the file or adding RAM - to resolve the issue.

In a structured change-management process, the very first step is to propose (or formally request) the change via a Request for Change (RFC). This ensures stakeholders review the need, assess risks, and determine the priority before any approvals, scheduling, or implementation occur.
