Correct Option: B

Responsible government is a conception of a system of government that embodies the principle of parliamentary accountability, the foundation of the Westminster system of parliamentary democracy. Governments (the equivalent of the executive branch) in Westminster democracies are responsible to parliament rather than to the monarch, or, in a colonial context, to the imperial government. If the parliament is bicameral, then the government is responsible first to the parliament’s lower house, which is more numerous, directly elected and thus more representative than the upper house.
