Herman Pontzer did the first ever comparative measurements of the bone structure of variety of African apes, which showed that human bone structure is essentially the same as that of an ape’s, having the exception of human pelvis that in becoming shorter, broader, and more bowl shaped supported erect posture and efficient bipedal locomotion.
A. which showed that human bone structure is essentially the same as that of an ape’s, having the exception of human pelvis that in becoming shorter, broader, and more bowl shaped supported
supported isn't the right usage since pelvis still supports the erect position till date
B. which showing that human bone structure is essentially the same as an ape, showed the exception of human pelvis that became shorter, broader, and more bowl shaped, supporting
showing isn't the right usage since it has already occured the study is showcasing it's result coupled with the usage of showed after the xomma is errorneous which distorts the event timeline therefore out
C. which showed that human bone structure is essentially the same as that of an ape, with the exception of human pelvis that has become shorter, broader, and more bowl shaped to support
The tenses are perfect and the meaning too is perfect therefore let us hang on to it
D. a study showing that human bone structure is essentially the same as that of an ape, and it had an exceptional human pelvis that became shorter, broader, and more bowl shaped, supporting
which is required however let us not dwell deep into that and still consider some other better reason to eleminate the inclusion of it in the passage gives us a meaning as though the study had a pelvis which isn't the case it's human that had the pelvis therefore without further adeu let us kick it out
E. a study that showed that human bone structure is essentially the same as an ape’s, the only exception being the human pelvis that became shorter, broader, and more bowl shaped and supported
and supported isn't the right usage since it distorts the requisite meaning
Therefore IMO C
