Explanation of options: (a) ✔ Correct; their flat design allows atraumatic clamping of uterine edges. (b) ✘ Cervix is held with tenaculum or vulsellum, not Green Armytage. (c) ✘ Cord is clamped with artery forceps or cord clamp, not this instrument. (d) ✘ Fetal head traction is done with obstetric forceps or vacuum, not Green Armytage.
