Answer:
Transcription of gene A is not affected
Explanation:
A transcriptional repressor is a DNA/RNA-binding protein that acts to suppress gene expression and/or protein synthesis by binding to target sequences. Moreover, a silencer is a DNA region that binds to particular transcriptional repressors in order to suppress gene expression. In this case, the transcriptional repressor is activated by binding to an effector molecule X (e.g., another protein). In consequence, and since the activated repressor-X complex is not more able to bind the silencer of gene A, it is expected that such complex will not be able to affect transcription of the target gene.
