Which meaning of kindle refers to starting a fire?

• A. To arouse an emotion or cause a feeling
• B. To build or light a fire
• C. To confuse or bewilder
• D. To extinguish a flame

Answer: (B)

Kindle means to light or ignite something, starting a fire. This is the literal use you’d have when you want to get a flame going—e.g., you kindle a campfire by lighting tinder and kindling. The other ideas are different senses of the word: it can be used figuratively to arouse interest or emotion, but it’s not about fire in that sense, and it can even be used in contexts that imply extinguishing a flame, which is the opposite of starting one. So the meaning that refers to starting a fire is to light or ignite a flame.
