Select and explain. 
A. Adequate exposal of posterior segment, B. Anterior segment is not visualized adequately, C. Superior exposure is very well exposed, D. Sciatic nerve injury in 10% in cases
C: Superior exposure is very well exposed
Answer: C: Superior exposure is very well exposed 
Explanation: (c) Superior exposure is very well exposed- Please observe this question is not the same as previous as Kocher-Langenbeck approach is not a good approach for superior segment as its visualization is limited hence D option will be considered acceptable as nerve injuries in earlier studies were more than 6% as compared to now.
