Final answer:
Nelson Mandela, Angela Merkel, and Justin Trudeau are all politicians recognized for communicating in an ethical manner, with Mandela known for his reconciliatory leadership post-apartheid, Merkel for her pragmatic leadership in Germany, and Trudeau for his dedication to ethics in government.
Step-by-step explanation:
The question asks about politicians known for communicating in an ethical manner. Nelson Mandela, Angela Merkel, and Justin Trudeau are often recognized for their ethical communication and leadership.
Nelson Mandela was a key political leader of the African National Congress (ANC) and the anti-apartheid movement in South Africa. After being imprisoned for twenty-seven years for his efforts to end the apartheid system, Mandela led South Africa as its first president in the post-apartheid era, and his presidency was marked by a commitment to reconciliation and ethical governance.
Angela Merkel, as the former Chancellor of Germany, is known for her pragmatic and ethical approach to leadership, often prioritizing the greater good over partisan politics throughout her long tenure.
Canadian Prime Minister Justin Trudeau has also been recognized for his dedication to ethical principles in government, although like all politicians, his approach has faced criticism and scrutiny.
Therefore, the answer to the question "Who are three politicians known for communicating in an ethical manner?" is D) All of the above.
