B. Increased carbon dioxide levels have made the oceans more acidic.

Explanation:

Carbon dioxide is increasing in the atmosphere due to human activities such as burning of the fossil fuels, deforestation and others. The carbon dioxide is responsible for the process of ocean acidification. It occurs when the carbon dioxide is readily absorbed into the oceanic water at high rate. The carbon dioxide reacts with water to form carbonic acid. Carbonic acid breaks down into a hydrogen ion (H+) and bicarbonate (HCO3-). The presence of all these hydrogen ions in water decreases it's pH, or produces acidity.

This process adversely affect the life of the marine animals like the acidic water causes the shells and skeleton composed of calcium carbonate to dissolve in water.

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.
