C. comma splice
D. complete sentence

... and please learn to spell "grammar" correctly.

The given statement, "There is a tube overlying the pelvis in the midline, degenerative changes are also noted in the lumbosacral spine," is a comma splice.

A comma splice occurs when two independent clauses (complete sentences) are mistakenly joined together using only a comma. In this case, "There is a tube overlying the pelvis in the midline" and "degenerative changes are also noted in the lumbosacral spine" are both independent clauses and should be separated by appropriate punctuation or connected with a coordinating conjunction.

To correct this comma splice, you can either use a period to separate the two independent clauses into separate sentences or use a coordinating conjunction (such as "and" or "but") after the comma to join the two clauses together.
