Suresh and Rajesh operate their grocery stores in the town of Tirur, Kerala. They both have a childhood friend, Brajesh, who has a small coconut farm on the outskirts of Tirur. Suresh and Rajesh have asked Brajesh to provide them with a continuous supply of coconuts for their shops. Brajesh started by providing 50 coconuts each to Suresh and Rajesh. Every time Brajesh returns from his farm to his home in the city, he replenishes the reduced quantity back to 50. As a result, Suresh and Rajesh never faced stock-out situations.

Based on this scenario, determine the method of replenishment for Suresh's and Rajesh's shops.

A) Electronic data interchange (EDI)-based ordering

B) Rationing based on past sales

C) Continuous replenishment program (CRP)
