Step 1: Look at the key phrase.
The phrase 'monopoly of legitimate force' is a famous signal. It points to the writer who studied authority and legitimacy.
Step 2: Link the phrase to a thinker.
Authority, legitimacy and bureaucracy are the main themes of Max Weber. His State has force as its special means, and the force is accepted as lawful by the people.
Step 3: Rule out the others by their main themes.
Marx is about class conflict and economic base. Durkheim is about social solidarity and social facts. Ambedkar is about caste, social justice and constitution making. None of these themes is about a monopoly of legitimate force.
Step 4: Pick the answer.
Only Weber fits, and he is the second name in the list, so the answer is option 2.
Step 5: Cross-check the result.
Double check with the way the lines read. The quoted sentence talks about the State as a body, about legitimate force and about a territory. Those three ideas appear together in Weber's writing on politics and authority, and in no other listed writer. Marx talks about class rule, Durkheim about social facts, and Ambedkar about caste and rights, so the choice of option 2 is safe.
Final Answer:
Weber gave this view of the State, option 2.
\[ \boxed{\text{Option 2}} \]
