Answer:
The correct option is (d)
Step-by-step explanation:
A password is a word or few words that helps in identifying a person during authentication process. Some of the rules for a strong and efficient password are as follows:
- It should be changed frequently.
- It should have a combination of upper and lower case letters and alpha numeral characters.
- A word with four or more characters found in a dictionary should not be contained in a password.
- Character length should be between 8 and 30.
As such, option (d) is incorrect as characters in a password should essentially be more than 8 but less than 30.
