The correct answer is option-D

The fossil record shows species suddenly appearing and disappearing. When one species goes extinct, another one usually takes its place.  It provides with the snapshots of the past. It shows the changes over the past four billion years. It maybe unclear at parts but it does provide evidence that life is old and over time has changed. By studying fossil record the relation of different plants and animals can be figured out and it also tells us how old life is on earth.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
