No, HCl acid does not react with copper. Only those metals whose standard reduction potentials are lower than that of hydrogen react with non-oxidising acids like HCl and dil.H

, and displace hydrogen from them. Copper has higher reduction potential (more positive) than hydrogen, and it does not react with HCl acid.

As shown in image copper is dipped in HCl and there is no reation at all thus Option B is correct.

Option B
Cu is less reactive than Hydrogen as found in the metal reactivity series. So, copper will not be able to displace hydrogen from HCl and hence, no reaction will occur.

I hope you understood.
