B. If you apply extreme heat to a diamond, it will burn and release carbon dioxide.

Answer 1

A run-on sentence is a type of sentence in which two or more complete sentences are not properly separated by punctuation.

Step-by-step explanation:

A run-on sentence is a type of sentence in which two or more complete sentences are not properly separated by punctuation. The correct run-on sentence among the options given is option A: 'Sprained ankles are common injuries for athletes a sprain may not even need treatment.'

In this sentence, the two complete sentences 'Sprained ankles are common injuries for athletes' and 'a sprain may not even need treatment' are not separated by any punctuation. To correct this run-on sentence, you could add a coordinating conjunction such as 'and' to separate the two complete sentences. The revised sentence would be: 'Sprained ankles are common injuries for athletes, and a sprain may not even need treatment.'

For instance, the sentence could be revised to "Sprained ankles are common injuries for athletes; a sprain may not even need treatment." or "Sprained ankles are common injuries for athletes, and a sprain may not even need treatment."
