Solution

The correct options are
A $M_{3} C_{60}$
B $Y B a_{2} C u_{3} O_{7}$
D $H g_{2} B a_{2} Y C a C u_{2} O_{7}$
Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature.
In a superconductor, the resistance drops abruptly to zero when the material is cooled below its critical temperature. An electric current flowing through a loop of superconducting wire can persist indefinitely with no power source.

$M_{3} C_{60}$ , $Y B a_{2} C u_{3} O_{7}$ and $H g_{2} B a_{2} Y C a C u_{2} O_{7}$ are superconductivity materials.

Hence, the correct options are $A$ , $B$ and $D$
