With whom would it be best for a privacy professional in an organization to consult...

Comprehensive and Detailed Explanation:

Privacy-Enhancing Technologies (PETs) are designed to protect individuals' privacy while allowing for the use and analysis of data. A privacy professional looking for guidance on PETs should consult an information technologist specializing in information privacy technology because they have expertise in both data privacy principles and the technical implementation of privacy solutions.

A specialist focused on AI (Option A) may have knowledge of AI-driven privacy risks but may not specialize in PETs.

An independent privacy technology advocate (Option B) may promote privacy-enhancing principles but may lack practical implementation expertise.

An engineer focused on security technology products (Option C) may prioritize cybersecurity without integrating privacy-by-design principles.

An information technologist specializing in information privacy technology (Option D) is the best choice because they have the required expertise in privacy technologies, data protection laws, and privacy-by-design implementation.
