Solution

The expressions that could make 'M' is the son of 'L' definitely false are:

  1. L/M: This means L is the son of M, which makes it impossible for M to be the son of L.
  2. L+M: This means L is the father of M, which contradicts the statement that M is not the son of L.
  3. L*M: This means L is the wife of M, which also contradicts the statement that M is not the son of L.
  4. LxM: This means L is the sister of M, which again contradicts the statement that M is not the son of L.
  5. L-M: This means L is the mother of M, which contradicts the statement that M is not the son of L.

So, all the expressions make 'M' is the son of 'L' definitely false.
