B) .60
C) 0
D) -.60

A correlation coefficient of 1.00 would indicate a perfect positive correlation where all children at all ages have the same reading speed, which is unlikely. A correlation coefficient of 0 indicates no correlation, but it does not account for patterns that may exist. A negative correlation (such as -.60) would suggest that as the age of the child increases, the reading speed decreases, which is also unlikely as children generally improve their reading speed as they get older. A correlation coefficient of .60 suggests a moderate positive correlation, indicating that as the age of the child increases, reading speed tends to increase. This is a likely pattern that could be observed in the data.
