The correct options are
A Well-defined financial system
B Good network of rivers and easy sailing of ships
C Indented coastlines and sheltered bays
In the second half of the 18th century, many towns experienced sudden population growth. People migrated to towns in search of jobs, London was the centre for international trade between Europe, America, Africa, and India, and England was suitable for harbours and ports due to indented coastlines and sheltered bays. The rivers of Britain were navigable, allowing small ships and boats to sail. By the end of the 17th century, Britain had a well developed financial system - several banks opened across the country to provide financial assistance.
