Match the column and select the correct option $:-$

Column-$I$	Column-$II$
$(a)$ Priestley	$(i)$ Sulphur bacteria
$(b)$ Engelmann	$(ii)$ Bell jar
$(c)$ Van Niel	$(iii)$ Aquatic plant
$(d)$ Ingenhousz	$(iv)$ Cladophora

Which scientist used aerobic bacteria,a prism,and green algae in his experiment?

Evaluate the following statements regarding $T$. $W$. Engelmann's experiment:
$1.$ $T$. $W$. Engelmann stated that chlorophyll present in algae absorbs light of green and orange colors,splits water molecules by photolysis,and releases $O_2$.
$2.$ Aerobic bacteria accumulate near the algae to utilize the released $O_2$.

Name two important researches of Priestley.

During photosynthesis,the oxygen evolved is released from $...........$.
