The incorrectly spelled word is "Labarotary."

The correct spelling is "Laboratory," which refers to a controlled environment used for scientific research, experiments, or testing.

The other options, "Presence," "Absence," and "Definite," are spelled correctly and have the following meanings:

• Presence: The state or fact of being present, existing, or available.
• Absence: The state or condition of being away or not present.
• Definite: Clearly or precisely defined, determined, or stated.
