Encryption protects sensitive information is explanation best explains the importance of using encryption. Personal information and important information are protected, and communication between client apps and servers is made more secure.
<h3>What is Encryption?</h3>
Encryption is a way of securing digital data that employs one or more mathematical procedures, as well as a password or "key" to decrypt the information.
Data is encrypted using an algorithm that makes the original data unreadable. The name of two different data comes from the fact that encryption and decryption are done with the same key.
Thus option C is correct.

Complete question;
<em>The distribution of lengths of salmon from a certain river is approximately normal with a standard deviation of 3.5 inches. If 10 percent of salmon are longer than 30 inches, which of the following is closest to the mean of the distribution? 26 inches A 28 inches B 30 inches C 33 inches D 34 inches</em>
Option B is correct. The value that is closest to the mean of the distribution is 30inches.
The formula for calculating the z-score is expressed as:
Given the following parameters
If 10 percent of salmon are longer than 30 inches, then:
Using the z table to get the value corresponding to the mean area 0.1.
- The required z-score will be -1.285
Substitute the resulting parameters into the formula to get the mean of the distribution.
Hence the value that is closest to the mean of the distribution is 30inches.
