Concept:A homophonic pair consists of two words that sound the same but may differ in meaning or spelling.
Explanation:First, recall that homophones are pronounced identically.
Option A: 'Kite' and 'Kit' are not pronounced the same. So they are not homophones.
Option B: 'Stare' and 'Stair' sound identical. They are homophones.
Option C: 'Principal' and 'Principle' are pronounced alike. They are homophones.
Option D: 'Steel' and 'Steal' also have the same pronunciation. They are homophones.
Therefore, only 'Kite-Kit' does not form a homophonic pair.
Answer:Option A. Kite-Kit
