Explanation:
Consider a stab wound in upper abdomen which has pierced through upper/ventral wall of stomach. This is what medically called as gastric perforation and requires emergency surgical management within 4 to 12 hours of injury. If left unattended the person will develope distension of abdomen with vomitting within 4 to 6 hrs, fever within 12 hrs, all because of infection spreading to rest of abdomen ( medically called Peritonitis). If no surgery is undertaken the person will die due to sepsis within 24 to 48 hrs.
Situation 2: stab would injuring major vessel or even liver will pool blood in abdomen ( medically Hemoperitonium) will further worsen the situation and wld need more intensive management. If not treated properly such person can die within 6 to 12 hrs due to hypovoluemic shock.

Answer:
The correct option is <em>B) ultraviolet region, especially below a wavelength of 320 nm.</em>
Explanation:
Ultraviolet light carries an enormous amount of energy in it. It is invisible to the human eye. When UV light with enormous energy and wavelength lesser than 320nm, hits the DNA, it causes changes in the structure of the DNA. Mostly, it affects the thymine nitrogenous base regions and forms pyrimidine dimers. The structure of the DNA changes on all the sites where dimers form and hence, they cannot be properly transcribed.
