Wave 1 in a scotopic ERG corresponds to which label?

Explanation:
In dark-adapted (scotopic) ERG, the retina’s first response to a light flash comes from the rod photoreceptors and appears as a negative deflection. This initial, negative wave is the a-wave, so Wave 1 is the A-wave in scotopic ERG. The next major deflection is the positive b-wave, produced mainly by inner retinal cells. The C-wave is a slower, later component, and photopic ERG refers to cone-driven responses rather than this dark-adapted first-wave sequence.
