(A) The experiment shown in the image is the famous 'Bell Jar Experiment' conducted by Joseph Priestley in $1774$.In this experiment,Priestley demonstrated that plants restore to the air whatever breathing animals and burning candles remove.He observed that a mouse kept in a closed space (bell jar) would soon suffocate and die,and a burning candle would soon extinguish.However,when he placed a mint plant in the same bell jar,the mouse stayed alive and the candle continued to burn.This led to the discovery of oxygen (which he called 'dephlogisticated air').
