In the field of online security, it’s commonly believed that longer passwords are inherently more secure than shorter ones. A recent study, however, suggests a different perspective. Cybersecurity experts analyzed data breaches and found that the complexity of a password (a mix of characters, numbers, and symbols) is often a more critical factor in security than length alone. They observed that passwords with higher complexity were less likely to be breached, even if they were shorter in length. The experts propose that focusing on password complexity, rather than length, could enhance online security.
Which of the following, if true, most supports the cybersecurity experts' conclusion?
A. Analysis of security breaches revealed that most compromised passwords, regardless of length, lacked a diverse combination of characters and symbols.
B. Statistical data shows that passwords based solely on common words, even if lengthy, are more frequently breached than shorter, more complex passwords.
C. Advanced password-cracking software has been demonstrated to break simple long passwords more quickly than shorter, but complex, passwords.
D. Research indicates that users tend to create longer passwords for more sensitive accounts, yet these passwords often follow predictable patterns.
E. A survey of password habits revealed that while users often choose lengthy passwords, they commonly reuse these passwords across multiple accounts, compromising security.

GMAT Club's Official Explanation:
C. Advanced password-cracking software has been demonstrated to break simple long passwords more quickly than shorter, but complex, passwords.
- This choice directly supports the conclusion by providing evidence that complexity in passwords is more effective against advanced cracking methods than mere length. It highlights that shorter passwords with higher complexity can be more secure than longer but simpler ones, aligning with the experts' viewpoint.
The other options, while relevant, do not as directly support the conclusion:
A. Analysis of security breaches revealed that most compromised passwords, regardless of length, lacked a diverse combination of characters and symbols.
- This option supports the idea that complexity is important but doesn’t specifically compare the effectiveness of complexity versus length.
B. Statistical data shows that passwords based solely on common words, even if lengthy, are more frequently breached than shorter, more complex passwords.
- This is a strong contender but focuses more on the weakness of long passwords based on common words rather than directly emphasizing the strength of complexity, as choice (C) does.
D. Research indicates that users tend to create longer passwords for more sensitive accounts, yet these passwords often follow predictable patterns.
- This highlights a common user behavior but doesn't directly compare the effectiveness of password complexity versus length.
E. A survey of password habits revealed that while users often choose lengthy passwords, they commonly reuse these passwords across multiple accounts, compromising security.
- This addresses an important aspect of password security (reuse of passwords) but doesn’t focus on the comparison between length and complexity.
Thus, choice (C) provides the strongest evidence in favor of the conclusion regarding the relative importance of password complexity over length.

Premise: passwords with complexity are less likely to breach irrespective of its length.
Conclusion: focus on password complexity rather than length.
we have to strengthen the conclusion.
A. Analysis of security breaches revealed that most compromised passwords, regardless of length, lacked a diverse combination of characters and symbols............................It's sort of saying what's already being mentioned in premise. reject.
B. Statistical data shows that passwords based solely on common words, even if lengthy, are more frequently breached than shorter, more complex passwords.............................We are not concerned about password based solely on common words
C. Advanced password-cracking software has been demonstrated to break simple long passwords more quickly than shorter, but complex, passwords.....................this seems to strengthen the conclusion. As advanced password cracking SW is also facing difficulty in cracking the complex password.
D. Research indicates that users tend to create longer passwords for more sensitive accounts, yet these passwords often follow predictable patterns...........................this is talking about user habit. Not relevant
E. A survey of password habits revealed that while users often choose lengthy passwords, they commonly reuse these passwords across multiple accounts, compromising security.........................reuse of password is irrelevant.
IMO OA should be C
