The correct order to form a meaningful sentence is ADCBE. Part A specifies the timing of the action declared by the university. Part D states that the university declared something. Part C specifies what the university declared (that it will increase something). Accordingly, DC forms a necessary pair. Part B comes next as it specifies what the university intends to increase, which is the tuition fees. Part E specifies the timeframe or context of the action, indicating that the increase will be applicable for the upcoming academic year. Hence, (b) is the correct answer.
The complete sentence is: At the beginning of October, the university declared its intention to increase tuition fees for the upcoming academic year.
