Contrast is important when designing a web page for many reasons. One of the most important reasons is because if you don't have contrast, you won't be able to read what is written on the page. Your eyes will have to strain really hard or it just simply won't be possible to read at all. Another really important reason is that contrast makes the web page look visually appealing. Whereas, if you don't have contrast it is all kind of jumbled together. As you can see there is a plethora of reasons contrast is important.

Answer:
C)An error message is issued.
Explanation:
If we try to open a file for reading when that file does not exist, we will get an error message.
For example, in Java we will encounter a FileNotFoundException as in the code below:
try {
FileInputStream fis = new FileInputStream("myFile.txt");
DataInputStream dis = new DataInputStream(fis);
BufferedReader br = new BufferedReader(new InputStreamReader(dis));
String str = null;
while ((str = br.readLine()) != null) {
System.err.println(str);
}
} catch (FileNotFoundException e) {
e.printStackTrace();
}
If the file myFile.txt does not exist we can expect to see an exception stack trace corresponding to FileNotFoundException.
The most common type of task performed by utility program is the file management. The utility program is a program created to help computer users in managing, optimizing, and configuring the computer. Every newly purchased computer has a file managing program to help users for setting the computer up for its personal use. Therefore, file managing is the most common utility program.
