65% of women with a bifid uterus, a uterus which is divided

Option A - INCORRECT.
This option has deviated from the argument and imposing a wrong information which was not sighted in the argument by saying,15% of women with a bifid uterus end up losing the fetus.

Option B - INCORRECT.
This is so true. In most cases, some causes of premature birth reside in factors other than the physiology of the birth mother but other factors stimulate the effect most time.

Option C - INCORRECT.
This option also supports the conclusion in this argument, going by the ratio of occurrence and the realistic outcome of the natural result, it is not judgmental to say that, a bifid uterus is not necessarily hereditary.

Option D - INCORRECT.
This option is the conclusion in this argument but does not give a valid reason for the possibility of the causes. The birth weight of premature infants whose mothers have a bifid uterus is lower than that of premature infants whose mothers do not have a bifid uterus is correct due to the statistics of occurrence recorded.

Option E - CORRECT.
This option best support the conclusion in this argument and there is a reason to think otherwise about it. Knowing that a bifid uterus is an uncommon condition among women and its more reasonable to justify that the percentage of possibility of 65% of women with a bifid uterus giving birth to premature children against the 95% of prematurely born infants whose mothers uterus is not bifid. Definitely, there is more reasons than thinking its a natural coincidence.
