Polymers are usually organic (but not necessarily).

• A. False
• B. True
• C. Always inorganic
• D. Never carbon-based

Answer: (B)

Polymers are large molecules formed by repeating units called monomers, and most of these monomers are carbon-based with other elements like hydrogen, so the resulting polymers are organic. There are exceptions—some polymers have inorganic backbones, such as silicon-oxygen or phosphorus-nitrogen systems—so polymers can be inorganic, though that’s less common. Because carbon-based polymers are the norm, the statement that polymers are usually organic (but not necessarily) is correct. The other options overstate or misstate the situation by claiming polymers are always inorganic or never carbon-based.
