The Ⓐ down is not an Impulse, only if it is truncated which is unlikely. What's left is a ZigZag down which has to be part of a Flat/Combo/MultiZZ.
The only way for this to become a valid correction then is for it to go through the Golden Zone as Ⓑ of Flat must retrace to .886 and Ⓧ must retrace to above the (B) of Ⓐ channel upper trendline (purple).
