Both options A) and B) are used to identify sedimentary rock.
The conditions the rock was formed under & the composition of the rock itself are used to identify sedimentary rock.
B) when it was formed, does not make [identifying] a rock sufficient. Same goes for C) where it was formed, this may help with the identification of a different rock (i.e.,igneous rock), but not sedimentary. As sediments basically make up this type of rock.

One major way to conserve non renewable resources is to cut down on your use of non-renewable resources by driving less, using less electricity, or buying fewer new things. Another way is to use more renewable energy sources or renewable resources such as wind, solar, or geothermal power. Another way is to seek to increase the efficiency of things that you use which consume power or non-renewables such as lightbulbs, your car, or other appliances. These efforts all seek to reduce the amount of non-renewable resources which are used to prevent green house gas emissions and the depletion of non-renewable resources.
By any standard the United Kingdom is among the most urbanized of countries, for towns not only typify the national way of life but are unusually significant elements in the geography of the country.
I would say Nato would be the most responsible answer.
