A. High coupling leads to good model quality provided all blocks in a structural model exhibit the same average degree of coupling

B. High coupling leads to poof model quality because it decreases reuse potential and prevents independent modification of system elements

C. Low coupling leads to poor model quality because all parts of a system must be properly coupled in order to measure the completeness of the model

D. Coupling has no bearing on model quality because no metrics exist for measuring the level of coupling of SysML models
