is this true ? please show steps

Given the following circuit study it carefully and answer the following questions Z In this circuits is A sal equivalent to Bsol (think carefully NO Output Z is sensitive to Input B when AC =0010.01 . Fault Coverage for these 2 test vectors (U1 and 000) are: 50% The fest vectors that can test Xsal are: ABC= 110.100.101 . The test vectors that can test B sal are: ABC=111 001010 101
