Explanation:

To solve this, we analyze the female reproductive system organs:

• Fallopian tubes (A) are narrow tubes for egg transport, not thick - walled with the described position.
• Vagina (B) is a muscular canal but has a different structure and position than described (between bladder and rectum with thick muscle and rich blood supply).
• Uterus (C) is a hollow, muscular organ in the pelvic cavity between the bladder and rectum, with thick muscle (myometrium) and rich blood supply, matching the description.
• Ovaries (D) are small, oval - shaped glands, not hollow muscular organs in that position.

C. uterus.
