Question

On the basis of definition, the Ustaqussat are:

• A. Solid (Jamid)
• B. Liquid (Sayyal)
• C. Mufrad (Single)
• D. Vaporous (Bukhari)

Hint:

Always remember — Ustaqussat are defined as Mufrad (Single), representing the simplest building blocks in Unani theory.

Answer 1

The Correct Option is C

In Unani medicine, the term Ustaqussat refers to the fundamental simple substances or elements which make up all matter.
By definition, these are called Mufrad meaning ‘Single’ or ‘Simple’.
The concept implies that Ustaqussat cannot be further divided into other elements by natural processes — they are the building blocks of physical matter.
Options like Solid (Jamid), Liquid (Sayyal), and Vaporous (Bukhari) describe the physical states or forms that matter can take, but they do not define what Ustaqussat are by their conceptual nature.
Therefore, the correct answer is Mufrad (Single), highlighting that Ustaqussat are the indivisible basic elements.
