​Fabric coated with rubber, oxidized oil or varnish produces​

Correct option is A

Fabric coated with rubber, oxidized oil, or varnish produces a waterproof finish. These materials are used to coat fabrics to make them impervious to water, creating a waterproof barrier that prevents moisture from penetrating the fabric.

Information Booster:
Waterproof finishes are applied to fabrics to make them resistant to water penetration, which is essential for products like raincoats, tents, and outdoor gear. Materials such as rubber, oxidized oil, or varnish are commonly used to coat fabrics, providing a waterproof layer without altering the fabric's basic structure. This treatment allows the fabric to remain dry even in wet conditions. While the coating provides waterproofing, it can also reduce breathability, so it is important to balance the waterproof properties with comfort in certain applications.

Additional Knowledge on Incorrect Options:

• Fireproof finish (Option B): A fireproof finish is typically achieved through chemical treatments such as flame retardants, not rubber or varnish coatings.
• Moth proof finish (Option C): Moth-proof finishes are usually achieved through insecticidal treatments or chemicals like naphthalene, not waterproof coatings.
• More than one of the above (Option D): This option is incorrect as only waterproof finishes are achieved with rubber, oxidized oil, or varnish coatings.
• None of the above (Option E): This is incorrect because a waterproof finish is the correct answer.
