Let Ax = b be a system of linear equations where A is an m x n matrix and b is an m x 1 column vector and X is an n x 1 column vector of unknown. Which of the following is false?
  • a)
    The system has a solution if and only if, both A and the augmented matrix [Ab] have the same rank.
  • b)
    If m < n and b is zero vector, then the system has infinitely many solutions.
  • c)
    If m = n and b is non-zero vector, them the system has a unique solution.
  • d)
    The system will have only a trivial solution when m = n, b is the zero vector and rank (A) = n
Correct answer is option 'C'. Can you explain this answer?
