Answer :
The direct consequence of British salutary neglect was an increase in the power and influence of colonial legislatures, as colonists became accustomed to self-governance and managing their own affairs with minimal British intervention.
The direct consequence of the British policy of salutary neglect in the American colonies was a growth in colonial legislatures, option (B). Salutary neglect allowed the colonies to self-govern and operate with minimal interference from the British government, fostering a strong tradition of self-rule.
The distance from the mother country meant the colonists became accustomed to managing their own affairs and expected lax enforcement of royal mandates. Colonial assemblies gained in power and significance as the colonists exercised their political rights, believing they could only be taxed by legislatures they themselves had elected.
This period of salutary neglect came to an abrupt end with the conclusion of the French and Indian War, leading to the British government's efforts to recoup war expenses through various acts imposing taxes on the colonies, sparking protest and eventually contributing to the American Revolution. Hence the correct answer is option B.
