"Bursting of pipelines due to closure by a valve".
Bursting can be a result of water hammer, but not its cause.
"Rapid pressure change due to a rapid change in the rate of flow". This is Exactly correct — this is the definition of water hammer.
"Pressure increase due to closure of a valve resulting in decrease in rate of flow". It's Close, but not as general or accurate as the correct answer.
Also implies a slower change, which would not cause hammer.
