To find out how spyware is more dangerous, we must know what each term mean.
Adware is a <em>software that automatically displays advertising material usually on a site that a user goes to</em>.
Spyware is a <em>unwanted software that steals your internet usage data and personal information</em>.
So while Adware can be extremely annoying, it is not as potentially harmful as Spyware, which can steal your personal information and potentially ruin your life.

Answer:
Option A is the correct choice answer for the above question.
Explanation:
The programming concept says that every function returns some value. If the return value is not defined by the user then the function returns the garbage value otherwise it returns the defined value by the user.
The return value is defined by the user with the help of the "return" statement and with the help of the following syntax-
return value; // The return statement.
Hence the option A is right because it satisfies the above concept while the other is not because--
- Option B states that it must be longer than one line which is not correct.
- Option C states that it cannot be longer than one line but this line does not make any sense about the returned statement.
- Option D states that it describes the parameter value which is the wrong definition about the returned statement.
