If a teacher asks students to write a grapheme that makes the sound /k/, what can they write?

The correct answer is that students can write all of the graphemes that make the sound /k/, which includes 'c', 'k', and 'q'. Each of these letters can represent the /k/ sound in different contexts within the English language.

For example, the letter 'c' can make the /k/ sound as in "cat," while 'k' produces the same sound in words like "kite." The letter 'q' also represents the /k/ sound, typically in combination with a 'u,' as seen in words like "quest." This versatility in spelling reflects the complexities of phonetics in English, where multiple graphemes can represent a single phoneme.

Understanding this allows students to appreciate the nuances of English spelling and phonetics, empowering them to decode and spell words more effectively.
