Passage3      Questions 11 to 15 are based on the following passage.     When we accept the evidence of our unaided eyes and describe the Sun as a yellow star,we have summed up the most important single fact about it-at this moment in time.It appears probable, however, that sunlight will be the color we know for only a negligibly(微不足道的)small part of the  Sun's history.       Stars, like individuals, age and change.As we look out into space,we see around us stars at all stages of evolution.There are faint blooded dwarfs so cool that their surface temperature is a mere 4,000 degrees Fahrenheit; there are scaring ghosts blazing at 100,000 degrees Fahrenheit and almost too hot to be seen, for the great part of their radiation is in the invisible ultraviolet range.Obviously, thedaylight produced by any star depends on its temperature, today (and for ages to come) our Sun is at about 10,000 degrees Fahrenheit, and this means that most of the Sun's light is concentrated in the yellow band of the spectrum, falling slowly in intensity toward both the longer and shorter light waves.          That yellowhump will shift as the Sun evolves,and the light of the day will change accordingly.(80) It is natural to assume that as the Sun grows older, and uses up its hydrogen fuel-which it is now doing at the spanking rate of half a billion tons a second-it will become steadily colder and redder.14 According to the passage, as the Sun continues to age, what color is it likely to become?
A

Yellow.

B

Violet.

C

Red.

D

White.
