Please suppose a woman who doesn't throw not necessary stuff away even after several years. Once when her son opens the storage room's door, he faces lots of not a confused mixture of old things of no use and value. He says:
Mom! The storage is full of.........but I don’t know why you don't have the heart to throw any of them out.
a) junk
c) bric-a-brac
d) mishmash
I would appreciate it if you could let me know which one of the above listed words sounds natural in this self-made sentence? I guess in spite of the fact that they all work here (based on dictionary definitions), there should be a fixed, more common term to refer to this type of things or at least one of these four choices sounds more common / natural. If so, then please let me know what is that term / word?
