A 22-year-old primigravida undergoes pelvic assessment in labor. Findings: narrow interspinous diameter and prominent ischial spines. Which pelvic type is this most consistent with?

Correct option is B

Android pelvis is characterized by narrow mid-pelvis, prominent ischial spines, and reduced interspinous diameter → pelvic inadequacy → obstructed labor risk.
Explanation of options: (a) ✘ Gynecoid = ideal female pelvis, widest midpelvis, least obstructed labor. (b) ✔ Correct; android pelvis = narrow midpelvis, pelvic inadequacy. (c) ✘ Anthropoid = long anteroposterior diameter, favorable for vaginal delivery. (d) ✘ Platypelloid = wide transverse, short AP, difficulty in engagement but not narrow ischial spines.
