The correct answer is B.

Formation of an embryo begins when the sperm cell meets an egg. When they meet, a zygote is first formed. A zygote is a single diploid cell created when two haploid cells merge.

The zygote begins to divide , and when this division starts, the zygote turns into an embryo. So an embryo is an organism that is at the early stages of development and which is not able to survive on its own.

The term embryo is used only to refer to eukaryotes or organisms that are multi cellular.

Answer from: Quest

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.
