D Is an Hourly Paid Worker

D is an hourly paid worker. D claims payment for hours which he has not worked in order to get compensation for work completed months ago which is as yet unpaid. Which of the following represents the law on dishonesty:

A) D will be dishonest because it is always dishonest to lie.
B) It will be entirely up to the jury as a question of fact as to whether D is dishonest.
C) D's conduct is objectively dishonest but if he genuinely believes himself to be acting honestly then he may have a defence.
D) The question of dishonesty is concerned with D's conduct and not his state of mind. Therefore his belief is irrelevant.
