Sentence correctness

Hi

Please tell me which of these is correct.

1. Goriot had brought with him a considerable wardrobe, the gorgeous outfit of a retired tradesman, who denies himself nothing.

2. Goriot had brought with him a considerable wardrobe, the gorgeous outfit of a retired tradesman who denies him nothing.

3. Goriot had brought with him a considerable wardrobe, the gorgeous outfit of a retired tradesman who denies himself nothing.

I think the answer is #1. I think so because I see the use of himself in the adjectival clause and comma before it to be appropriate.

But the answer given in the book is #2.

Please give your views.
