Which of These Was NOT a Conclusion in the Review

Which of these was NOT a conclusion in the review by Carré and Archer (2018) of research on testosterone administration and aggressive behaviour?

A) Testosterone administration increases aggressive behaviour more in competitive than non-competitive situations
B) Testosterone administration increases aggression more in high-dominance than low-dominance men.
C) Short-term administration of testosterone is more likely than long-term administration to increase aggressive behaviour
D) The findings support the theory that high levels of testosterone are of value to men in competitive situations (e.g., sexual selection)
E) This theory is excessively narrow in that it de-emphasises social factors associated with gender differences in aggression
