The Correct Option is A
Solution and Explanation
Step 1: Define transverse lie. Lie describes the relationship between the long axis of the fetus and the long axis of the uterus. In a transverse lie the fetal long axis lies perpendicular to the maternal spine, and when it lies obliquely it is called an oblique lie.
Step 2: Determine the presenting part. With the fetus lying across the uterus, neither the head nor the breech occupies the lower pole. Instead the shoulder comes to lie over the cervical opening during labour. Both transverse and oblique lies are therefore grouped together as shoulder presentations.
Step 3: Eliminate distractors. Face, vertex, and brow are all presentations seen in a longitudinal (cephalic) lie where the head presents, so they are not features of a transverse lie. The presenting part in transverse lie is the shoulder.
Hence the correct answer is option 1.
