Concept:Rubber production involves harvesting latex from rubber trees and converting it into usable solid rubber through specific stages.
Explanation:First, identify the processes listed in the question.
Process I, coagulation, is a necessary step because liquid latex must be turned into solid rubber by adding coagulating agents such as formic acid.
Process III, tapping, is the method of cutting the bark of the rubber tree to collect the white latex.
Both of these processes are directly connected with rubber production.
Process II, fermentation, is not used in rubber production.
Fermentation is associated with making products like beer, wine, or some food items, not with latex processing.
So, the processes that belong to rubber production are coagulation and tapping only.
Out of the given options, this combination appears in option B.
Answer:B. I and III only
