Step-by-step explanation:
The subject of this question is English. The question is asking about two phonemes /ch/ and /j/ that differ from affricatives because they stop air before releasing it. The correct option to fill in the blank is C) Palatal.
Phonemes /ch/ and /j/ are both palatal consonants. They are produced when the middle of the tongue approaches the palate or roof of the mouth. Unlike affricatives, which are made by combining a stop with a fricative sound, these palatal phonemes involve a stop of air before releasing it.
