Answer:
According to Lamarck's theory the mutation in the somatic cells would also be carried from the parents to the children.
But, Darwin's theory states that the somatic mutations are not carried to another generation. Only germ line mutations are carried from one generation to another.
Since, losing a leg during leg injury is not related to germ line so it would not be carried from parent to children.
This statement is true according to Darwin but false according to Lamarck's theory.
