Which of the following statements is true about cookies?
a. Is always enabled.
b. Is permanent information.
c. By default, it lasts for one day only.
d. None of the options.
The correct answer and explanation is :
Correct Answer: d. None of the options.
Explanation:
Cookies are small text files stored on a user’s computer by a web browser at the request of a web server. They are commonly used to remember information about the user, such as login status, preferences, or tracking identifiers.
Let’s analyze each option:
a. Is always enabled.
This statement is false. Cookies are not always enabled. Users can configure their browsers to block cookies, allow only certain types of cookies (e.g., first-party cookies), or prompt before saving cookies. Additionally, with increasing awareness of online privacy, many browsers and users now block or delete cookies regularly.
b. Is permanent information.
This statement is false. Cookies can be either session-based or persistent.
- Session cookies are temporary and deleted when the browser is closed.
- Persistent cookies can last longer, depending on the expiration date set by the website. However, they are not truly permanent — users can manually delete them at any time, and some browsers automatically clear them periodically.
c. By default, it lasts for one day only.
This statement is also false. Cookies do not have a universal default lifespan.
- If a cookie does not have an expiration date, it becomes a session cookie and is deleted once the session ends (when the browser closes).
- If a cookie does have an expiration date set, its duration depends on the specified date. It could last minutes, days, months, or even years — not just one day by default.
Conclusion:
All the given options are inaccurate in their general claims about cookies. Therefore, the correct answer is d. None of the options, as none of the statements accurately describes the behavior or characteristics of cookies in all scenarios.
