The correct answer is D

Aqueous flare - The release of protein following breakdown of the blood-aqueous barrier renders the aqueous no longer optically clear. The path of a light shone across the anterior chamber is defined in the aqueous. A sharp focussed beam and careful observation are needed. Aqueous flare is usually transient.

To see aqueous flare an intense and focal light source must be held close (1 cm) to the corneal surface. A direct ophthalmoscope set at its smallest circular aperture of white light, and to its highest light intensity, works best (a pen light is inadequate for this procedure). Aqueous flare is present if the light beam is visible in the anterior chamber.
