Verified step by step guidance1
Understand that biological classification is a system used to organize and categorize all life forms. It is hierarchical, meaning it starts from the broadest category and narrows down to the most specific.
Familiarize yourself with the main levels of classification in biology: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Recognize that the broadest level of classification is the 'Domain'. There are three domains: Bacteria, Archaea, and Eukarya.
Compare the given options: Domain, Phylum, Class, and Kingdom. Identify which of these is the broadest level.
Conclude that 'Domain' is indeed the broadest classification level, encompassing all forms of life into three major categories.
