Right Answer is C


When the menstrual cycle is in the late proliferative phase and nearing ovulation, the cervix will secrete a clear, thin mucoid discharge. The discharge may be described by patients as looking like a raw egg white. These changes in cervical secretions make the vagina less acidic and create a less hostile environment for the sperm to reach the uterus in order to conceive.There are crypts within the cervix that allow for the secretion of this cervical mucus during the late proliferative phase.After ovulation occurs, the cervical mucus will become thicker and will be harder for the sperm to penetrate through.
