• B. Wax
• C. Oleo-resin
• D. Fixed oil

Hint:

Fixed oils, like castor oil, do not evaporate and are typically derived from seeds.

Answer 1

The Correct Option is D

Step 1: Understanding castor oil.
Castor oil is a non-volatile oil that is derived from the seeds of the castor bean plant (*Ricinus communis*). It is considered a fixed oil, meaning it does not evaporate like volatile oils.
Step 2: Analyzing the options.
(A) Volatile oil: Volatile oils, such as essential oils, evaporate easily and are not fixed oils. Castor oil is not a volatile oil.
(B) Wax: This is incorrect, as castor oil is not a wax.
(C) Oleo-resin: Oleo-resins are a mixture of oil and resin, which does not apply to castor oil.
(D) Fixed oil: Correct — Castor oil is a fixed oil, meaning it is not volatile and remains stable at room temperature.
Step 3: Conclusion.
The correct answer is (D) Fixed oil as castor oil is a fixed, non-volatile oil.
