The argument is that “it should be illegal to let your child work in show business”.
1 – Wrong
Break-ups and mental breakdowns are not related to the main argument of the text. Therefore, this is wrong. 1 does not give a flaw in the argument that it should be illegal to let your child work in show business.
2 – Wrong
Again, addictions and broken relationships is not the main theme of the text. 2 does not find a flaw in the argument.
Since both statements are wrong, D is the answer.
