Which organization name corresponds to the acronym PECI?

• A. Portland Environmental Compliance Initiative
• B. Portland Energy Conservation Institute
• C. Portland Energy Conservation Inc.
• D. Portland Efficiency and Conservation Initiative

Answer: (C)

Acronyms are built from the exact words in the official name, including the suffix that designates the type of entity. In this case, PECI is the four-word sequence Portland, Energy, Conservation, and I, where the final letter comes from the suffix that is actually used in the organization’s registered name. The widely used and officially registered name for this acronym is Portland Energy Conservation Inc., with Inc. signaling Incorporated. That exact combination of words and the legal suffix matches PECI, making it the best fit.

Other options would require a different legal form or a different final word, such as Institute or Initiative, which would change the official name and are not the commonly recognized name associated with the PECI acronym in this context.
