The correct answer is Mediolateral.

The mediolateral episiotomy, cut from the midpoint of the fourchette directed downward and outward (usually to the right) at about 45°, is the most commonly performed type (DC Dutta) because it rarely extends into the anal sphincter.

The median (midline) cut heals well but carries a higher risk of 3rd/4th-degree extension; lateral and J-shaped incisions are rarely used because of bleeding and injury to Bartholin's duct.

Short trick: Most common and safest = mediolateral.
