B
They do not contain carbon-hydrogen bonds.
C
They are synthesized by plants.

Verified step by step guidance1
Understand the definition of inorganic nutrients: Inorganic nutrients are substances that do not contain carbon-hydrogen (C-H) bonds, distinguishing them from organic compounds.
Identify the key characteristic of minerals: Minerals are inorganic nutrients, meaning they lack carbon-hydrogen bonds.
Evaluate the given options: Analyze each option to determine which one aligns with the definition of inorganic nutrients.
Option analysis: 'They are composed of carbon-based compounds' suggests organic nature, which is incorrect for minerals. 'They do not contain carbon-hydrogen bonds' correctly describes inorganic nutrients. 'They are synthesized by plants' and 'They are derived from living organisms' imply organic origins, which are not applicable to minerals.
Conclude with the correct characteristic: The defining feature of minerals as inorganic nutrients is that they do not contain carbon-hydrogen bonds.
