Answer:
The most appropriate answer would be the first option.
The given description best describes the structure of Bicornuate uterus, that is, heart-shaped uterus.
It is a hollow structure made up of three tissue layers. The large canal (cervix) extends from the lower part of the uterus which connects it to the vagina.
In addition, two fallopian tubes (one from each ovary) connect to the uterus.
The fertilized egg or zygote from the fallopian tube is delivered to the uterus where it gets implanted into the endometrium layer.
The uterus protects and nourishes the developing embryo until it is ready for birth.
