Answer: A) -0.95
The closer the value of r is to either -1 or +1 means that we have very strong correlation. In this case, r = -0.95 is closest to -1 compared to the other values. Also, no other value is really close to +1, so we can ignore it.
With r = -0.95 very close to -1, it means that there's a strong negative correlation. The higher the age, the less number of text messages the person sends. As age (x) goes up, the number of text messages (y) goes down.
