Strong passwords typically combine upper and lower case letters, numbers and special characters and avoid obvious words or sequences. The chosen example has mixed characters and is longer than trivial strings, making it harder to guess. It does not directly reveal personal information like name or date of birth. Therefore, it best follows recommended guidelines.
Option A:
This option correctly illustrates complexity and unpredictability, which help resist brute force and dictionary attacks. It is also reasonably long, which enhances security further.
Option B:
The word โpasswordโ is one of the weakest choices and is often tried first by attackers. It is widely discouraged in all ICT security training.
Option C:
Simple numeric sequences like 123456 are easily guessed and frequently appear in leaked password lists. They offer almost no protection.
Option D:
A common word like โcollegeโ is vulnerable to dictionary attacks and becomes even weaker if it reflects the userโs environment.
