What is a fossil fuel?

an atmosphere in which visibility is reduced because of a cloud of some substance
fuel consisting of the remains of organisms preserved in rocks in the earth's crust with high carbon and hydrogen content
Twins who develop from two separate fertilized eggs. They are genetically no more similar than brother or sisters but they have the same fetal environment
the combining of images from the two eyes to form a single visual percept

The correct answer is: fuel consisting of the remains of organisms preserved in rocks in the earth's crust with high carbon and hydrogen content

A Option A is describing smog, not a fossil fuel. C: Option C is describing fraternal twins, not a fossil fuel. D: Option D is describing binocular vision, not a fossil fuel. A fossil fuel is a type of fuel that is made from the remains of living organisms that have been preserved in rocks in the earth's crust. These fuels, such as coal, oil, and natural gas, have high carbon and hydrogen content and are formed over millions of years through a process called fossilization. This is different from option A, which is describing pollution caused by chemicals in the atmosphere. Option C is also incorrect because it is describing a biological process, not a type of fuel. Finally, option D is incorrect because it is describing how the brain processes visual information, not a type of fuel.
