Dedicated AC line - Contractor wants to use BX instead of romex

I’m having a dedicated in wall AC cable run, about 40-50 ft. I was planning on using VH audio cryo’d 10-2 Romex but the contractor wants to use BX since it’s an urban area and more impervious to mice, etc.

Any thoughts on this?

Also I was planning on wiring the end of the run with an 20 Amp IEC connector so I could plug it directly into my Niagara 7000. I don’t know if they will wire it this way but I thought I could always do that myself later.

Contractor said that mice or rats can eat through romex, which didn't concern me.    I'll have to find out what local NYC code is.

Thanks for all the replies so far (except that nasty one).   In doing some research it seems BX (named for the Bronx, where it was invented) is required in buildings like mine (over 3 stories).

So any suggestions on a particular metal clad cable to use?  (Steel or aluminum?).  I know there is an oversize neutral cable but the increased diameter would be to hard to work with in my situation (requires some 90 degree bends.    I imagine someone might cryo BX?
