With his attention to the efficient use of resources,
the king has _____ researches on the development of energy sources
in the country on a comprehensive scale.
(A) concentrated (B) conducted
Please help me. Thanks a lot.
I would say that the king has not personally carried out the research, so 'conducted' is not a great fit. He has probably concentrated the research on the desired area rather than on others. However, I would strongly question the use of the word 'researches'.

However, I would strongly question the use of the word 'researches'. The mass noun, 'research', is very rarely turned into a conventional plural. Keep it as 'research'.
