d. "According to National Breast Cancer Foundation researchers, in their October 2004 article titled, 'NBCF Supports M. D. Anderson Cancer Center's Breakthrough Cancer Research', found at www.nationalbreastcancer.org..."
This option provides specific attribution to the organization, includes the date and title of the article, and still references the website, making it a comprehensive oral citation.
