Wastage of perishable farm produce is likely due to the following problems except

The question is asking for the problem that is NOT a cause of wastage of perishable farm produce. The answer is "inadequate water supply in rural areas". This is because water supply, although important for agricultural activities, is not directly linked to the issue of perishable farm produce wastage. The other options are directly linked to the problem, as inadequate storage and processing facilities can lead to spoilage, poor roads leading to rural areas can cause delays and damage to produce during transportation, and inadequate plying of rural roads can lead to difficulties in transporting produce to markets on time.
