B) 0.60
C) 0
D) -0.60

A correlation coefficient of 1.00 would indicate a perfect positive correlation, which is not realistic in this case as reading speed will likely vary among children of the same age. A correlation coefficient of 0 would indicate no relationship between age and reading speed, which is also unlikely as older children are generally able to read faster than younger children. A negative correlation coefficient of -0.60 suggests that as age increases, reading speed decreases, which is not necessarily true for all children. The most likely scenario is a positive correlation between age and reading speed, but with some variation. Therefore, a correlation coefficient of 0.60 would be the best choice as it represents a moderate positive correlation between age and reading speed among children who are able to read.
