[单选题]Text 2 Pretty in pink:adult women do not remember being so obsessed with the colour,yet it is pervasive in our young girls'lives.It is not that pink is intrinsically bad,but it is such a tiny slice of the rainbow and,though it may celebrate girlhood in one way,it also repeatedly and firmly fuses girls'identity to appearance.Then it presents that connection,even among twoyearolds,between girls as not only innocent but as evidence of innocence.Looking around,I despaired at the singular lack of imagination about girls'lives and interests.Girls'attraction to pink may seem unavoidable,somehow encoded in their DNA,but according to Jo Paoletti,an associate professor of American Studies,it is not.Children were not colourcoded at all until the early 20th century:in the era before domestic washing machines all babies wore white as a practical matter,since the only way of getting clothes clean was to boil them.What's more,both boys and girls wore what were thought of as genderneutral dresses.When nursery colours were introduced,pink was actually considered the more masculine colour,a pastel version of red,which was associated with strength.Blue,with its intimations of the Virgin Mary,constancy and faithfulness,symbolized femininity.It was not until the mid1980s，when amplifying age and sex differences became a dominant children's marketing strategy,that pink fully came into its own,when it began to seem inherently attractive to girls,part of what defined them as female,at least for the first few critical years.I had not realized how profoundly marketing trends dictated our perception of what is natural to kids,including our core beliefs about their psychological development.Take the toddler.I assumed that phase was something experts developed after years of research into children's behavior:wrong.Turns out,according to Daniel Cook,a historian of childhood consumerism,it was popularized as a marketing trick by clothing manufacturers in the 1930s.Trade publications counselled department stores that,in order to increase sales,they should create a“third stepping stone”between infant wear and older kids'clothes.It was only after“toddler”became a common shoppers'term that it evolved into a broadly accepted developmental stage.Splitting kids,or adults,into evertinier categories has proved a surefire way to boost profits.And one of the easiest ways to segment a market is to magnify gender differences—or invent them where they did not previously exist.
It can be concluded that girls'attraction to pink seems to be_____
A.clearly explained by their inborn tendency
B.fully understood by clothing manufacturers
C.mainly imposed by profitdriven businessmen
D.well interpreted by psychological experts
