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.

"The prominent bony ridge that you can palpate across the posterior surface of the scapula is the <em>scapular spine"</em>.

This is a <em>bony formation</em> that <em>goes from medial to the lateral</em> side of the scapula <em>and finishes</em> in one of the extremes as a bulky prominence called <em>acromion</em>.
The spine is easily palpable through the skin.
