Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Wednesday (day of discovery)
Why it's wrong here
The 72-hour clock starts at discovery.
- ✓
Saturday
Why this is correct
The GDPR mandates that a data controller must notify the relevant supervisory authority of a personal data breach without undue delay and, where feasible, no later than 72 hours after becoming aware of it. Since the organisation discovered the breach on Wednesday, the 72-hour period commences from that point. Counting forward, 72 hours from Wednesday leads directly to Saturday, making it the precise deadline for notification under these regulations.
- ✗
Thursday
Why it's wrong here
72 hours from Wednesday is Saturday, not Thursday.
- ✗
Monday (day of breach)
Why it's wrong here
Notification is based on awareness, not occurrence.
