GMTG is a hair processing method that involves the use of acidic chemicals, such as thioglycolic acid. These chemicals are categorized as low pH levels, typically in the range of 4.5-6.5. This low pH level is necessary for the hair to be broken down and remolded into the desired shape. So, the option that best aligns with a low pH level is A Acid wave.

Furthermore, the other options, B: Base wave, C: Neutral wave, and D: Alkaline wave, do not align with a low pH level. Base waves have a higher pH level, typically around 9.0, and are used for creating more dramatic curls. Neutral waves have a pH level of around 7.0 and are used for minimal wave and curl formation. Alkaline waves have the highest pH level, typically around 10.0-11.5, and are used for strong curl and wave formation. Therefore, these options are incorrect and do not align with the low pH level typically associated with GMTG.
