A

B
Old
Explanation: 

Detailed explanation-1: -A forest is a renewable resource but it takes much more time to grow a forest than to grow a stand of trees.

Detailed explanation-2: -It suggests old-growth forests be considered non-renewable resources and be protected from logging because it takes hundreds of years for the forests to return to their previous status as massive carbon sinks. Scientists cited by environmentalists say that huge, old-growth trees store massive amounts of carbon.

Detailed explanation-3: -Natural resources such as coal, petroleum (crude oil) and natural gas take thousands of years to form naturally and cannot be replaced as fast as they are being consumed.

Detailed explanation-4: -There are four major types of nonrenewable resources: oil, natural gas, coal, and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels. Fossil fuels were formed within the Earth from dead plants and animals over millions of years-hence the name “fossil” fuels.
