What is the best and most important practice to avoid a crash?

Answer: C — Be aware of your surroundings

The most effective and crucial practice to avoid a crash is to be aware of your surroundings. While other choices such as refraining from texting and driving and abiding by traffic laws are important, if a driver is not aware of their surroundings, they may not be able to react in time to avoid a potential crash. Constantly honking your horn is not a recommended practice as it can startle or distract other drivers, potentially causing a crash.
