The choice identifying bacteria, parasites, fungi, and viruses as primary types of attentional biological hazards is correct because these organisms represent some of the most significant biological threats to human health in various environments. Each of these groups can lead to serious infectious diseases, respiratory problems, or allergic reactions, particularly in environments where mold and other biological contaminants are prevalent.

Bacteria are ubiquitous and can cause infections by entering the body through wounds or ingestion. Parasites, which can take forms like protozoa and helminths, often invade human hosts and can result in chronic illness. Fungi, including molds, are critical to consider in mold remediation contexts due to their ability to produce mycotoxins, which can severely affect health. Viruses, being microscopic pathogens, can lead to contagious diseases and often thrive in damp environments, where mold may also proliferate.

The other choices include organisms that are either too specific or grouped in ways that do not cover the full spectrum of primary biological hazards. For instance, algae and worms are less critical in the context of immediate health risks associated with mold and biological contamination in structures. Therefore, the initial option presented encompasses a broader and more relevant category of biological hazards that someone involved in mold remediation would need to be aware of.
