Final Answer:
a) dizziness"Vertigo" is best represented by "dizziness" as it specifically entails a spinning sensation or perception of movement, aligning closely with the characteristic experience of vertigo.
Step-by-step explanation:
"Vertigo" is commonly associated with a spinning sensation or a feeling of movement when one is stationary. Among the provided options, "dizziness" best captures this characteristic of vertigo.
While the other options such as "light-headedness," "giddiness," and "instability" may convey a sense of imbalance or disorientation, they don't precisely convey the spinning sensation associated with vertigo.

Dizziness, in a broader sense, refers to a feeling of unsteadiness or disorientation. However, in the context of vertigo, it specifically refers to the perception of movement or spinning, making "dizziness" the most accurate match among the given options. Therefore, the correct choice is a) dizziness.
