Correct Answer: dignified

Solution : The correct choice is the fourth option .

Ignoble is an adjective that is used to describe someone who lacks honour. It refers to actions or behaviour, considered shameful or not respectable.

Dignified is an adjective that is used to describe someone who possesses a sense of nobility and honour and thus deserves respect. Both of these words imply opposite behaviour and, hence, are antonyms.

The meanings of the other options are as follows:

• A corrupt person is someone who is guilty of dishonest practices.
• Craven is used for someone who is very cowardly.
• Abject is used to describe situations that are miserably bad.
