Answer : $D$ Friday.
Read symbol $← $ as word before,
- ${\color {Red} {The\space day}}$ before ${\color {Pink} {The\space day}}$ before ${\color {Magenta} {Yesterday}}$, Is $3$ days after ${\color {Blue} {Saturday}}$
${\color {Red} {The\space day}}$ $←$ ${\color {Pink} {The\space day}}$ $←$ ${\color {Magenta} {Yesterday}}$ $←$ ${\color {Green} {Today}}$
${\color {Blue} {Saturday}}$ $→$ ${\color {Cyan} {1 \space Day}}$ $→ $ ${\color {Orange} {2 \space Day}}$ $→ $ ${\color {Red} {3\space day}}$
$\therefore$${\color {Blue} {Saturday}}$ $→$ ${\color {Cyan} {1 \space Day}}$ $→ $ ${\color {Orange} {2 \space Day}}$ $→ $ ${\color {Red} {The\space day}}$ $←$ ${\color {Pink} {The\space day}}$ $←$ ${\color {Magenta} {Yesterday}}$ $←$ ${\color {Green} {Today}}$
$\therefore$${\color {Blue} {Saturday}}$$→$${\color {Cyan} {Sunday}}$$→$${\color {Orange} {Monday}}→$${\color {Red} {Tuesday}}$$←$${\color {Pink} {Wednesday}}$$←$${\color {Magenta} {Thursday}}$$←$${\color {Green} {Friday}}$
