Both will lead to a hydrocele thus it is improtant to carefully read the stem. You will notice that it says "cystic structure is found in the scrotum." This is key to answering this question

In D, both the superior and inferior aspects of the process vaginalis is obliterated leaving a cystic cavity in the middle with fluid. Whereas in C, there is a free communication between the scrotum and pertinonium which allows peritonial fluid to enter the scrotal sac.

Hope that helps.

i think you mixed the options, ur explanation for C should be for D and vice versa.
