Step 1: Historical Context of the Deccan Ryots:
In the $19^{\text{th}}$ century, peasant cultivators (ryots) in the Deccan became heavily dependent on local moneylenders (sahukars). Moneylenders manipulated account books, charged exorbitant compound interest, and kept peasants in a state of permanent indebtedness.
Step 2: Introduction of the Limitation Law of 1859:
To check this ruway accumulation of interest and establish a transparent system, the British passed the Limitation Law in $1859$. The core clause of this law stated that any loan bond signed between a moneylender and a ryot would remain valid for a maximum period of only three years.
Step 3: Unintended Consequences:
The law had severe negative consequences for the peasants. To bypass the three-year limit, moneylenders began forcing the ryots to sign a new bond every three years. During this renewal process, the moneylender would combine the unpaid interest of the previous three years with the origil principal to create a new, vastly inflated principal amount. Thus, the correct option is (C).
