B. Ascending and descending colons.
C. Transverse and descending colons.
D. Descending and sigmoid colons.
E. Transverse and sigmoid colons.
The ascending and transverse colons will be impaired due to injury because Blood from the superior mesenteric artery and parasympathic nerve fibres from the vagus nerve is collected by the ascending and transverse colon.
