In the following questions two columns are given containing three sentences/phrases each. In first column, sentences/phrases are A, B and C and in the second column the sentences/phrases are D, E and F. A sentence/phrase from the first column may or may not connect with another sentence/phrase from the second column to make a grammatically and contextually correct sentence. Each question has five options which display the sequence(s) in which the sentences/phrases can be joined to form a grammatically and contextually correct sentence. Choose the pair(s) which make(s) a grammatically meaningful sentence.

A-E: "The government is planning to boost a rise in unemployment rates..." → Illogical and contextually incorrect.
A-D: "The government is planning to boost the lack of transparency..." → Illogical and negative in context.
C-E: "The recent survey reveals a arise in unemployment rates across the country."(Grammatically incorrect (double use article 'a').
B-D: "Several experts have criticized the lack of transparency in project execution."(Grammatically and contextually correct.)
