B. Merriam-Webster's collegiate dictionary (10th Ed.). (1993). Springfield, MA: Merriam-Webster Inc.
Step-by-step explanation:
As you can see in the image I added you need to write the author's name first, surname first and initials after a coma, then the date published in parentesis, then the title of the source, the location of the publisher columns and the publisher's name and finally if it's an online resourse the URL from where it was retrieved is listed at the end. When there's no author the name of the organization is used.
