The correct option is B Welfare state
The Labour Party introduced the welfare state after World War II. Clement Attlee, the Labour Prime Minister who succeeded Winston Churchill in 1945, transformed Britain into a welfare state. The Labour Party introduced social programs that provided public housing and established old-age pensions, unemployment insurance, and the creation of a National Health Service, or free medical care. The Conservatives, under Margaret Thatcher in 1979, began to roll back the welfare state. England has had a parliamentary-type democracy since 1689. It has never followed a communist or corporate form of government. The Labour Party nationalized the Bank of England but did not introduce communism to England.
