Choose the word closest in meaning to the word 'TRANQUIL'.

Tranquil describes a state that is peaceful and free from disturbance, so 'calm' is the nearest meaning. 'Turbulent' is the opposite, while 'dreary' (dull and cheerless) and 'distant' (far away) do not convey peace. Use the sound of the word in a sentence such as a tranquil lake to confirm it. Think of the word in a sentence first, and then pick the option that could replace it without changing the meaning; watch out for the antonym placed among the options.
