Explanation written with AI and checked against the answer key

Step 1: Analyze the question The question asks for the name given to the process of changing the structure (shape or form) of a commodity so that it becomes more useful or satisfying.

Step 2: Explain the concept In Economics, utility is the satisfaction a person gets from consuming a good or service. Production is often described as the creation of utility. There are different types:

  • Form utility: created when raw materials are changed into a finished product (e.g., cocoa beans processed into chocolate, timber turned into a chair).
  • Place utility: created when goods are moved from where they are plentiful to where they are needed (e.g., transporting yams from Benue to Lagos).
  • Time utility: created when goods are stored until they are needed (e.g., storing grains after harvest and selling them during the off-season).
  • Marginal utility: the extra satisfaction gained from consuming one more unit of a good. It is not a type of production activity.

  • Changing the structure of a commodity means changing its form.

  • B: Form utility involves changing shape or structure. Correct.
  • C: Marginal utility is about additional satisfaction from an extra unit. Wrong.
  • D: Place utility involves location or transportation. Wrong.

Step 4: Answer The correct option is B. Form utility.

Exam tip: Match the keyword to the utility type:

  • Structure, shape, or processing → Form
  • Movement or transport → Place
  • Storage or waiting → Time
  • Extra unit → Marginal
