During the period of salutary neglect, the rights outlined in the Magna Carta and the English Bill of Rights regarding taxation and representation were significantly strengthened in the colonies through the actions of colonial assemblies. These assemblies began to assume the right to tax citizens, effectively establishing a form of self-governance and a precedent for the expectation that taxation should require the consent of the governed, similar to the principles laid out in the Magna Carta and the English Bill of Rights.
Therefore, the correct response is:
Colonial assemblies assumed the right to tax citizens.
