Why each option

Intercepting a VoIP call involving a third party without consent violates Criminal Code of Canada Sections 184 and 542, which prohibit unlawful interception of private communications.

AAnalyzing internal firewall router software for vulnerabilities

Analyzing internal firewall or router software for vulnerabilities is passive reconnaissance that does not involve intercepting communications and falls within the agreed scope.

BExploiting application vulnerabilities on end-user workstations

Exploiting application vulnerabilities on in-scope end-user workstations is a standard authorized pentest activity covered by the hold-harmless agreement.

CAttempting to crack passwords on a development server

Attempting to crack passwords on an in-scope development server is an authorized activity under a properly executed penetration testing agreement.

DCapturing a VoIP call to a third party without prior noticeCorrect

Section 184 of the Criminal Code of Canada makes it illegal to willfully intercept private communications without the consent of at least one party to the communication. Section 542 extends similar protections to radio-based and packet-based communications such as VoIP. Capturing a VoIP call that involves a third party outside the scope of the engagement violates these statutes because the hold-harmless agreement only covers the hiring company and its assets - not third-party callers who have not consented.
