• B. elastic
• C. malleable
• D. soft

Answer 1

Answer: (A), (B)

The correct options are
A hard
B elastic

Vulcanization or vulcanisation is a chemical process for converting natural rubber or related polymers into more durable materials by the addition of sulfur or other equivalent curatives or accelerators. These additives modify the polymer by forming cross-links (bridges) between individual polymer chains. This makes rubber hard and elastic.
