3 types of asbestos

• A. Chrysotile
• B. Amosite
• C. Crocidolite
• D. Chrysotile, Amosite, Crocidolite

Answer: (D)

Asbestos isn’t a single mineral but a group of minerals, with three forms commonly discussed in safety contexts: chrysotile (white asbestos), amosite (brown asbestos), and crocidolite (blue asbestos). The choice that lists all three is best because it correctly identifies the three distinct types most often referred to in exams and health literature. Chrysotile belongs to the serpentine family and has curly fibers, and it was the most widely used. Amosite and crocidolite are amphiboles with straight, needle-like fibers that are more durable and biopersistent, making them generally more hazardous. There are other lesser-used asbestos minerals as well, but the standard classification usually centers on these three.
