float price;

$\}$;

typedef struct telephone mobile;

Which are correct ways to define and initialize a variable mobile m$?($Check all that apply!$)$

Group of answer choices

mobile m $=\{"$Apple$","$A$15",999\mathrm{.}99\}$;

mobile m $=["$Apple$","$A$15",999\mathrm{.}99]$;

struct telephone m $=("$Apple$","$A$15",999\mathrm{.}99)$;

struct mobile m $=\{$ "Apple", $"$A$15",999\mathrm{.}99\}$;

struct telephone m $=\{"$Apple$","$A$15",999\mathrm{.}99\}$;
