Correct Answer is C

Explanation

A. This description relates more to a sensory discrimination test, not graphesthesia.

B. This option does not accurately describe the graphesthesia test, which involves identifying shapes or numbers rather than just touch location.

D. This option describes a two-point discrimination test rather than graphesthesia, which focuses on identifying drawn shapes or numbers.
