(A) In $1770$,Joseph Priestley performed a series of experiments that revealed the essential role of air in the growth of green plants. He observed that a mouse kept in a closed space (bell jar) would soon suffocate and die. Similarly,a burning candle would soon get extinguished in a closed space. However,when he placed a mint plant in the same bell jar,he found that the mouse stayed alive and the candle continued to burn. Based on these observations,he concluded that plants restore to the air whatever breathing animals and burning candles remove.

Which scientist proposed the hypothesis that 'plants restore to the air whatever breathing animals and burning candles remove'?
