b) False
The statement "The House of Commons represented all British subjects, wherever they were in the world" is not true. The House of Commons is the lower house of the Parliament of the United Kingdom and represents the interests of the citizens of the United Kingdom. It is made up of Members of Parliament (MPs) who are elected by the people of the UK.
The House of Commons does not represent British subjects who are living outside of the United Kingdom. Instead, the representation of British subjects living outside of the UK depends on the specific circumstances. For example, British citizens living in certain overseas territories, such as Gibraltar or the Falkland Islands, may have their own elected representatives who represent their interests.
In summary, the House of Commons represents the citizens of the United Kingdom and not all British subjects worldwide.
