B) False because r is closer to 1

Step-by-step explanation:

A perfect negative correlation is seen as r=-1, since the answer r=0.997 is positive and very close to 1, this is almost a perfect POSITIVE correlation. Since the question asks about a negative correlation it is false, and the reasoning is because it is closer to 1 than 0. If it was closer to 0 than it would be a "low" correlation but not negative. The answer is B.
