Answer:

A. Manganese dioxide

Read Explanation:

  • Manganese dioxide is the primary catalyst used in the laboratory to accelerate the decomposition of hydrogen peroxide or potassium chlorate to produce oxygen gas.

  • It speeds up the chemical reaction by lowering the required activation energy while remaining chemically unchanged at the end of the process.
