* Understanding Multileader Components: * Multileader annotations consist of a leader line and a block (circle in this case). * The display of these components is influenced by their layer and color settings. * Layer and Color Settings: * The leader portion appears blue because it is on the LEADERS layer which is set to blue. * The circle block appears green because its content is on Layer 0 and set to ByBlock. This means the block takes on the properties of the layer it is inserted on unless overridden. * Combination of Color Settings: * Option D: ByLayer for the leader and Green for the block results in the leader being blue (from the LEADERS layer) and the block being green (explicitly set to green). * Option B: ByLayer for both the leader and block means the leader is blue (from the LEADERS * layer) and the block inherits the green color set in its definition. * Conclusion: * The two correct combinations to achieve the described color settings are ByLayer Green and ByLayer ByLayer.
