Step 1: Verify statement I and IV regarding content
Statement I is true: The text is indeed divided into 80 chapters. Statement IV is also true: It covers a vast range of subjects including religion, philosophy, festivals, astronomy, alchemy, manners, customs, social life, weights, and measures.
Step 2: Verify statement II regarding language

Step 3: Verify statement III regarding structure
Statement III is true: Al-Biruni adopted a unique methodology where he started each chapter with a question, followed this with a description based on Sanskrit traditions, and concluded with a comparison with other cultures.
