In Latin, ‘foresta' means ___________.

In Latin, ‘foresta' or 'forestis' means 'open wood'.

Forest is a large area covered with trees. The major product of forest is the wood. In medieval Latin, 'foresta' or 'forestis' was used as 'open wood' meaning an open woodland or wooded open area. When we compare the two, we understand forest is actually an open area dominated by wood (of the trees).

Hence, option C is correct.
