Could use help on a question

[Brandon Snyder]

Hey all, I'm working on my take-home midterm, and I was wondering if I could get your opinion on something.  This question has got me stumped and I can't find the answer in my textbook...

A homeowner preparing his home for sale should do all of the following except:

a) fix any broken fences and railings

b) replace worn carpeting

c) prune trees and mow lawns

d) repaint interior walls in a bright primary color

My group thinks it's D, but what do you professionals think? 

Thanks!

Brandon
