A Weighted Industry Attractiveness Assessment Is Generally Analytically Superior to an Unweighted

A weighted industry attractiveness assessment is generally analytically superior to an unweighted assessment because

A) a weighted ranking identifies which industries offer the best/worst long-term profit prospects.
B) an unweighted ranking doesn't discriminate between strong and weak industry driving forces and industry competitive forces.
C) it does a more accurate job of singling out which industry key success factors are the most important.
D) an unweighted ranking doesn't help identify which industries have the easiest and hardest value chains to execute.
E) the various measures of attractiveness are not likely to be equally important in determining overall attractiveness.
