Explanation

Encryption is the core mechanism of ransomware-it is used both as the attack payload (encrypting the victim's files to make them inaccessible) and as an evasion technique (encrypting malicious code or C2 communications to bypass signature-based detection and network inspection tools). By encrypting its payload, ransomware can evade antivirus scanners that rely on known byte signatures. Encoding (A) is a reversible data transformation with no cryptographic security and is a weaker evasion method. Resource exhaustion (C) is a denial-of-service technique, not an evasion method. Extended sleep calls (D) are used to evade sandbox analysis by outlasting the sandbox's analysis window, but this is not the primary or defining evasion technique associated with ransomware.
