user18965: Suppose below is target difficulty:
0x0000CDEF0A000000000000000000000000000000000000000000000000000000

So result value must lower than target to select block.
So, If Miner 'A' found:
0x000000000000000000000000076898778ABEFDC34798734590349843BDCAE854

Will miner 'A' can satisfy target difficulty or not?
And if not then please tell me the reason.
Thanks

user5757: Yes.  The test is that in order to be a valid proof of work, the hash found must be numerically less than or equal to the target.  That is certainly true of the hash found by Miner A in your example.
