Correct option is C
Teachers need to re-select, re-define and re-interpret text material while teaching.
The statement that written texts are subject to a multiplicity of reading and meanings implies that there is no single, definitive meaning of any text. This means that teachers cannot simply rely on the textbook to provide a complete and accurate understanding of the topic. Instead, they need to actively engage with the text, re-selecting, re-defining, and re-interpreting it in order to make it meaningful for their students.
