Please answer the question based on the following passage. You need to choose one letter from the given options, A, B, C, or D, as the final answer, and provide an explanation for your choice. Your output format should be ###Answer: [your answer] ###Explanation: [your explanation]. ###Passage:The secret of the “age” of human male and female ancestors is hidden in the Y chromosome and mitochondria.The Y chromosome only passes from father to son, while mitochondria only pass from mother to daughter.Looking back through these two genetic materials, we can find that all men have a common male ancestor "Y chromosome NAME_1", and all women have a common female ancestor "mitochondrial NAME_2".The researchers conducted genome sequencing and comparative analysis of 69 males from nine different populations, such as Asia, Africa, and Latin America, and found that this male common ancestor "Y chromosome NAME_1" was formed about 156,000 to 120,000 years ago.Using the same technical analysis of mitochondria, the researchers also calculated that this female common ancestor "mitochondrial NAME_2" was formed between 148,000 and 99,000 years ago. ###Question:Which of the following is most appropriate as a corollary of the above discussion? ###Options: (A)"Y chromosome NAME_1" and "mitochondrial NAME_2" were formed in the same period, and "age" is close, "Y chromosome NAME_1" may be earlier. (B)15 years ago, there was only one man "NAME_1" on earth (C)As two individuals, "NAME_1" and "NAME_2" should never meet (D)Men and women are born together and have conceived modern humans together
