If there is no info on the wire and termination temp you must use 60C for 100 amps and less. 110.14(C)

Also #12 is limited to 20 amps except for a few instances. 240.4(D)
Thats true but i don’t think that applies to this question. It makes complete sense now that you explained it , no further info was given so 60 degrees must be used. Thank you

#12 is limited to 20 amps by 240.4(D) for a water heater regardless of wiring method. Even if you had a 75° C wiring method like MC cable you're still limited to 20 amps even though for #12 AWG at 75° C the ampacity is 25 amps.

Why doesn't it apply to this question? What, in this question, makes you think that it doesn't apply.
I stand corrected

Still end up with 10 AWG being required because of 240.4(D), even when 75 C ampacity table is allowed to be used.
sorry didn't read all posts before replying.
