Answer:
Rationalisation
Explanation:
Rationalisation is the attempt by an individual to justify an action, behaviour, or attitude with logical reasoning. Mostly the reasons given are not appropriate enough.
In the given instance Jake is accused of stealing food products from the store, he justifies his act by claiming that his monthly pay is not sufficient to support his family of five members.
This is not enough reason to still but he still tries to rationalise his action based on his low salary.
