Answer: Artistic type of person
Explanation: The artistic type of personality, according to Holland, is one of six personality types. Given that it is stated that Brian is very creative and that after a week he can deal with his garden and its redesign without seeing anyone and without even noticing it, means that he is an artistic personality because is apart from being creative he is also independent. People who are social, for example, depend on society and other people for their social and personal needs, while the artistic type of personality is completely independent in their artistic and creative inspiration. Brian is busy redecorating his garden, which is further proof that he belongs to a mentioned personality type, because apart from other traits such people show good skills when it comes to crafts, and crafts are certainly needed when gardening is concerned.
In addition, this type of personality is adept at writing, music, dance, architecture, art, theatre, and they are also original, so it can be assumed that Brian will redesign his garden in an original way, because such people do not like repetition.
