BIn A, "that" is correctly used without commas to introduce a defining relative clause, specifying which report is being discussed. In B, "which" is also correctly used without commas for a defining relative clause, though "which" can sometimes imply a non-defining clause, it's acceptable here due to the absence of commas. C is incorrect because "that" should not be used with commas in defining relative clauses.
