A Spearman's rank correlation coefficient of -0.9872 indicates a very strong negative correlation between the two variables. However, correlation does not imply causation, so we cannot conclude that there is a causal connection between the two variables. The two variables are clearly not uncorrelated (choice C), and we do not have any information about whether the samples are random (choice D).
