Option (B) is incorrect because the agricultural marketing system primarily includes:
Assembling: Collection of produce from farms.
Storage and Transportation: Safeguarding and moving produce to markets.
Processing: Converting raw produce into finished goods.
Grading and Packaging: Preparing produce for sale.
Distribution: Delivering goods to consumers or retailers.
Option (B) incorrectly includes Production, which is a part of the agricultural sector but not of the marketing system. Marketing begins only after production is completed.
