Statements a,b,c are given Find which of the following statements are true

For an n x n matrix A which of the following statement(s) is (are) true? (a) Cofactor C31 cannot be equal to minor A31- (b) If C₁₁ C12 = C13 = ... = (c) If Ax=0 has trivial solution then det A=0. H Only b is true Only a is true a and c are true Only c is true None of them is true Cin=0, then A is invertible.
