The answer for this one would be A because
A cell in prophase I of meiosis has twice as much DNA as each of the daughter cells following cytokinesis of meiosis II.
Meiosis is reduction cell division through which gametes (eggs or sperm cells) are formed. Reduction division means that four haploid cells (n) are produced from a single diploid cell (2n). The number of chromosomes is reduced by half during meiosis but during fertilization are returned to the full numer, when the two gametes fuse.
I think the correct answer would be trench. An continental margin that is active would possibly have a trench while the passive one would never have one. Hope this answers the question. Have a nice day. Feel free to ask more questions.
