Answer:
A. Demonstrating that phonemes are represented by letters.
Step-by-step explanation:
Phonemes are speech sounds made by the mouth. These are the sounds that distinguish the meaning of words from one another which are represented by letters. The activity that the teacher pursues here contributes foremost in demonstrating the children that the individual sounds i.e. phonemes are represented by letters which would assist the children to recognize a sound through its representation in the form of letters. This would further lead to inculcating phonemic and phonological awareness among them.
