Which of the following words should be learned as sight words?

Learning sight words is a crucial component of reading instruction, particularly for individuals with dyslexia. Sight words are typically those that appear frequently in texts and may not always follow standard phonetic patterns, making them difficult to decode using conventional strategies. As such, they are often memorized so that readers can quickly recognize them without needing to sound them out.

The words "who," "friend," and "night" all fit into the category of sight words. "Who" is an irregular word that doesn't follow typical phonetic rules, meaning that students cannot easily sound it out. "Friend" is a common word that also does not conform neatly to phonetic patterns, particularly due to the silent 'i' and the way 'fr' is pronounced. Similarly, "night," while it has a phonetic component, contains the silent 'gh' and requires memorization for fluent reading.

By learning "who," "friend," and "night" as sight words, learners can improve their reading fluency and comprehension, as they will be able to recognize these words instantly when they encounter them in texts. Therefore, the correct answer encompasses all the options provided since each word should be memorized to aid in overall reading development.
