Answer:
Huffman code is use for encoding the language. The entropy when calculated is 1.5.
Explanation:
Using Huffman Coding scheme to encode:
The huffman coding scheme is described in the attachment.
To find entropy; we use the formula given below:
H = ∑
where H = Entropy and p = probability
p(A) = 50% = 1/2
p(B) = 25% = 1/4
p(C) = 25% = 1/4

According to security evaluation, <u>Penetration testing</u> is a level beyond vulnerability testing, a set of security tests and evaluations that simulate attacks by a malicious external source (hacker).
Penetration testing is often considered or described as ethical hacking. It involves the process of securing a firm or organization's cyber defenses.
The process of penetration testing or security testing includes assessing for exploitable vulnerabilities in networks, web apps, and user security.
Hence, in this case, it is concluded that the correct answer is <u>Penetration testing.</u>
