The correct option is
B. waeconline@yahoo.co.uk.
Explanation of Why Option B is Correct
-
Understanding Email Address Structure:
An email address typically follows the format
local-part@domain. The local part is the username, and the domain is the mail server that handles the email. For example, in the email address username@example.com, username is the local part, and example.com is the domain.
-
Breaking Down Option B:
- Local Part:
waeconline is the local part of the email address.
- Domain:
yahoo.co.uk is the domain part.
-
The
@ symbol separates the local part from the domain, which is a requirement for a valid email address.
-
Valid Characters:
- The local part can include letters, numbers, and certain special characters (like periods, hyphens, and underscores).
-
The domain part must include at least one period and can consist of letters, numbers, and hyphens.
-
Conclusion:
Since
waeconline@yahoo.co.uk adheres to the standard email format and contains valid characters, it is a valid email address.
Explanation of Why the Other Options are Incorrect
- Option A: www.itbeginswithu.org
-
This is a web address (URL), not an email address. It lacks the
@ symbol and a local part, which are essential components of an email address.
-
Option C: www.waeconline.org
-
Similar to Option A, this is also a web address. It does not contain an
@ symbol or a local part, making it invalid as an email address.
-
Option D: www.fine.gov.ng
- Again, this is a web address. It does not follow the email format and lacks the necessary components (local part and
@ symbol).
Common Pitfalls
- Confusing web addresses (URLs) with email addresses. Remember that email addresses must have the
@ symbol and a local part.
- Not recognizing that valid email addresses can have various domain extensions (like .com, .org, .co.uk, etc.), but they must always follow the
local-part@domain structure.
Revision Summary
- A valid email address must follow the format
local-part@domain.
- The local part can include letters, numbers, and certain special characters.
- The domain must include at least one period and can consist of letters, numbers, and hyphens.
- Always check for the presence of the
@ symbol to differentiate between email addresses and web addresses.
