The correct option is B dash
The context of the sentence I is about leaving a small line that would be filled in by the requisite word, like we do in fill in the blanks. Context of second sentence is that person was expected to rush to the place after hearing the news. So, the word that is best fit for both the sentences is 'dash'. Dash means to rush or run in a hurry. Also, a small line that is filled for fill in the blanks is also called Dash. Option B 'Blank' cannot be used because it doesn't fit in the second sentence. Option C 'Void' means.empty or invalid. Option D 'Bustle' means to do any activity in a busy manner . Option E 'Intervene' means to get involved in something. None of these words in options B, C, D and E can be used at both places. Thus, the best fit for both the sentences is 'Dash', Option A.
