Multifetal pregnancies with triplets occur at a rate of 1 in 8,100 births, but twins occur much more frequently with a rate of:
A- 1 in 85 births.
B- 1 in 5400 births.
C- 1 in 2700 births.
D- 1 in 540 births.

Correct Response: A

Twins, whether monozygotic or dizygotic, occur at the rate of about 1 in every 85 births. This rate has seen increases due to various reasons, such as the frequency of fertility treatments and women waiting until later in life to have children; older women, defined as over 35 years old, are more likely to carry multiples than younger women.
