Hint: The mullerian duct is also known as paramesonephric duct. It is a paired duct which gives rise to female reproductive organs, such as the oviduct, uterus, cervix and upper vagina.
Complete answer:
In this question, we have asked about the bulletin duct. So first we'll learn about the mullerian duct. The mullerian ducts are paired embryonic ducts. Paramesonephric ducts are present on the embryo of both sexes. They will develop in the female and form the oviduct, uterus, cervix and upper vagina and degenerate in males. The mullerian ducts form the upper female genital tract and itself develop into the fallopian tubes at their ends and fuse to form the uterus and upper part of the vagina. The mullerian duct forms almost all parts of the female reproductive tract but they first convert into fallopian tube or oviduct and form other organs after fusing to each other. So, we can. Say the mullerian duct is fallopian tube or oviduct.
So, the correct option is D. Oviduct.
Additional information: In some males, mullerian duct persists, thus is called mullerian duct persistence. It is a disorder of sexual development in which the men have normal male reproductive organs and they also have a uterus and fallopian tubes.
Note:
Mullerian duct is called paramesonephric duct because it is mesodermal in origin. It forms all the structure of the female reproductive tract but it is called oviduct because the mullerian duct itself changes into oviduct then fuse and grows downwards and forms the other organ from the fused oviduct.
