Which among the following is the commonest twin presentation?

The most common presentations at admission for delivery are cephalic-cephalic, cephalic-breech, and cephalic- transverse. Compound, face, brow, and footling breech presentations are relatively common, especially if fetuses are small, amniotic fluid is excessive, or maternal parity is high. The presentation can often be asceained by sonography. Ref: Cunningham F.G., Leveno K.J., Bloom S.L., Hauth J.C., Rouse D.J., Spong C.Y. (2010). Chapter 39. Multifetal Gestation. In F.G.
