Respuesta :
The correct option is B. The sentence that demonstrate correct use of the semicolon is"there have been many accidents during airshows; for example, last year the wind toppled a tent and equipment on top of bystanders."
Here the semicolon is connecting two separate independent sentences which are not linked with a conjuction and that is a fundamental rule to apply correctly the semicolon. In this case, the semicolon is separating the main part of the sentence, which introduces the topic, from the example provided in order to support the statement.
