Cybersecurity focuses on protecting systems, networks, and data from unauthorized access, damage, or disruption. Key knowledge points include the CIA triad (Confidentiality, Integrity, Availability), threat types (malware, phishing, DDoS, insider threats), and defensive controls (authentication, authorization, encryption, firewalls, intrusion detection, patch management, and incident response).

Step-by-step reasoning:
1. Define the domain: Cybersecurity’s primary goal is to ensure confidentiality (only authorized users access data), integrity (data is accurate and unaltered), and availability (authorized users can access services when needed).
2. Identify common activities: To meet those goals, cybersecurity implements technical and organizational measures such as strong passwords and multi-factor authentication (authentication), role-based access control (authorization), encryption for data-in-transit and at-rest, regular vulnerability scanning and patching, network segmentation, security monitoring, and incident response planning.
3. Link to the options: The first option—“Protecting systems and data from cyber threats and unauthorised access”—directly matches the CIA triad and the defensive controls listed above. It is a concise statement of cybersecurity’s central concern.
4. Address non-applicable options:
   - “Improving user interface design to reduce unwanted usage” relates to usability or UX design, not cybersecurity’s primary focus (though secure design overlaps with UX).
   - “Increasing website traffic using protected gateways” describes marketing or traffic engineering; protected gateways (like proxies) are security tools but increasing traffic is not a security objective.
   - “Maintaining cloud storage quotas for authorized users” is an administrative/storage management task, not the central aim of cybersecurity (quota management may be part of operations, not security control).

No numeric calculations are required for this conceptual question.

Because cybersecurity’s central mission is to defend systems and data against cyber threats and unauthorized access, the correct answer is: Protecting systems and data from cyber threats and unauthorised access. This matches the provided answer.
