Answer:
Option C.
Step-by-step explanation:
Prime Minister who enforced the Navigation Acts, is the right answer.
George Grenville was a member Parliament of Britain since 1742. However, following the end of the Severn Year's War, he became the Prime Minister of Britain. When he came to the post he found that the British government was heavily in debt.
Explaining his absence of finesse, George Grenville described the colonies of America as the 'least taxed community throughout the world' and ordered them to pay a high share of the war debt through taxes. To implement such policy of taxation he told the navy to rigorously execute the Navigation Laws.
