End product of 'aerobic' decomposition are:

  1. Unstable

  2. stable

  3. reactive

  4. Non Combustible
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Aerobic decomposition results in stable end products like carbon dioxide, water, and nitrates, which are not prone to further rapid decay. Unstable products are typically associated with incomplete or anaerobic processes.
