What Does Modern Evidence Suggest in Comparing Spearman's Concept of G

What does modern evidence suggest in comparing Spearman's concept of g and Thurstone's concept of primary mental abilities?

A) The concept of g has been rejected, because there is strong evidence that there are dozens of specific intelligences.
B) The concept of g is supported by evidence that cognitive skills are highly correlated, but there is also evidence that there can be specific strengths or deficits.
C) The concept of primary mental abilities has been rejected because each of Thurstone's categories can be explained by varying degrees of g.
D) Neither view has support, because it has been determined that Spearman underestimated and Thurstone overestimated the number of mental abilities.
