Question

Read the following statement and mark the correct answer

I. Artificially prepared synthetic fibre which resembles silk is known as terylene.

II. Rayon is not considered a synthetic fibre as it is regenerated from cellulose.

III. Bottles and jars are made up of PET.

• A. Statement I is false, II and III are true
• B. Statement I is true, II and III are false
• C. Statement I and II are false, III is true
• D. Statement II is true, I and II are false

Answer 1

The correct option is A Statement I is false, II and III are true

1. Terylene is a synthetic polyester fibre whereas rayon is artificial silk

Thus, statement $I$ is false.

2. Rayon was the first manufactured fibre. It is made from wood pulp, a naturally occurring, cellulose-based raw material. But it requires chemical processing. So, rayon is neither considered a synthetic fibre nor a natural fibre. Instead, it is considered to be a semi-synthetic fibre. Thus, statement $II$ is true.

3. PET is used to made bottles and jars. Thus, statement $III$ is true.

Hence, the correct option is $\text{A}$
