Step 1: Outline the general process of making jam from fresh fruit.
The process involves cleaning and preparing the fruit, cooking it to break it down and concentrate it, adding ingredients to ensure it sets properly, and then heating to the final setting point.
Step 2: Place the given steps in a logical order.
D. Washing: This is the very first step to clean the raw fruit and remove any dirt or residues.
B. Chopping: After washing, the fruit must be prepared by peeling, coring, or chopping it into smaller pieces.
A. Heating: The prepared fruit is then heated, usually with some water, to soften it and release its natural juices and pectin.
C. Addition of acid and pectin: After the initial heating, sugar, additional pectin (if needed), and acid (like lemon juice) are added. The mixture is then boiled rapidly to the setting point (around 105\(^\circ\)C). This step must come after the initial heating but is part of the overall cooking process. The most logical sequence is that the main heating/boiling phase (A) encompasses the addition of other ingredients (C). However, in the given options, they are separated. The common procedure is to heat the fruit first, then add sugar/pectin/acid and continue heating.
\end{itemize}
The sequence D \(\rightarrow\) B \(\rightarrow\) A \(\rightarrow\) C represents this flow: Wash the fruit, chop the fruit, heat the fruit pulp, then add setting agents and finish cooking. This matches option (1).
