B. dreams for survival 

lack of sleep will affect your body performance because your body was not able to rest properly and the energy you have already extended has not been restored by proper hours of sleep.

the required number of hours for sleep must be observed in order for your body to regenerate the energy you have expended. Lack of sleep results to low energy which results to slow reflexes.

Notice that when you are very tired, you tend to bump into things even though you knew beforehand that there are obstacles in your way. This is a primary example of what lack of sleep will cause you. You also experience black outs, where your mental state shuts down but your body is still awake. 

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite   shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
