Question

Which of the following matches is/are CORRECT?

• A. Surface fibre – Cotton – Gossypium hirsutum
• B. Bast fibre – Flax – Corchorus capsularis
• C. Drying oil – Safflower oil – Helianthus annuus
• D. Non-drying oil – Castor oil – Ricinus communis

Hint:

Surface fibres come from the outer part of the plant, while bast fibres are obtained from the inner part of the stem. Castor oil is a non-drying oil, while safflower oil is a drying oil.

Answer 1

The Correct Option is A, D

Step 1: Understanding the plant materials and their types.
- Surface fibre refers to the outer fibres of plants, and cotton (Gossypium hirsutum) is the correct plant that produces surface fibres.
- Bast fibre refers to the fibre obtained from the stem of plants, and flax (Linum usitatissimum) is the correct plant for bast fibre, not Corchorus capsularis.
- Drying oils are oils that harden upon exposure to air, and safflower oil (Carthamus tinctorius) is indeed a drying oil, but it is not the correct plant associated with drying oil.
- Non-drying oils are oils that do not harden easily, and castor oil (Ricinus communis) is the correct non-drying oil plant.

Step 2: Conclusion.
The correct answers are (A) and (D).
