Complete step by step solution: Here in the given question statement the question is regarding the working of the electric cell and the conversion of energy that takes place within. This signifies the working principle and the function of the cell. Now we have to conclude the answer step by step covering the cell.
The first kind of electric cells known as simple electrical cells were first developed in \[1800s\] . They are also referred to on multiple occasions as the galvanic cells. This is because they were invented by an Italian scientist, named as Luigi Galvani.
Wind winnowing is a method developed by ancient cultures for separating grains from chaff. It is also used to remove weevils or other pests from stored grains.
In its simplest form, it involves throwing the mixture into the air so that the wind blows away the lighter chaff, while the heavier grains fall back down for recovery. This includes techniques like using a winnowing fan (a shaped basket shaken to raise the chaff) or using a tool (a winnowing fork or shovel) on a pile of harvested grain.
The right option is option C, Winnowing.
Note: In Saxon settlements such as one identified in Northumberland as Bede's Ad Gefrin (now called Yeavering) the buildings were shown by an excavator's reconstruction to have opposed entries. In barns a draught created by the use of these opposed doorways was used in winnowing. The technique developed by the Chinese was not adopted in Europe until the \[18th\] century.
