Verizon [17]

because the total time for restoration is lengthy, peat can be considered a fossil fuel. The correct option is B.

<h3>What exactly are fossil fuels?</h3>

  1. peat is a fossil fuel because rewetting it takes only 3-5 years.
  2. peat is a fossil fuel because the total time for restoration is lengthy.
  3. peat is not a fossil fuel because it has biologic origins, making it a biofuel.
  4. peat is not a fossil fuel because humans can promote the replenishment of peat.

The restoration process of peat takes a long time of more than 100 years. As a result, because the total time for restoration is lengthy, peat can be considered a fossil fuel.

Thus, the correct option is B.
