Which statement about the mechanism of imine formation from a primary amine and an aldehyde or ketone is false?

A) The first steps involve addition of the amine to the carbonyl carbon to form a tetrahedral intermediate.
B) The last steps involve elimination of water to form a carbon-nitrogen p-bond.
C) All steps are reversible.
D) The reaction involves S_N2 displacement of the carbonyl oxygen by the amine nitrogen.
E) The reaction does not require a strong acid catalyst.
