(C) Step $1$: $James \ Watson$ and $Francis \ Crick$ proposed the double-helix model of $DNA$ in $1953$.Step $2$: $Maurice \ Wilkins$ and $Rosalind \ Franklin$ provided the $X$-ray diffraction data that was crucial for determining the structure.Step $3$: $Erwin \ Chargaff$ provided the base-pairing rules ($A=T$ and $G=C$), which were essential for the model.Step $4$: $Meselson$ and $Stahl$ performed the experiment in $1958$ to prove the semi-conservative mode of $DNA$ replication, which occurred after the model was proposed.Step $5$: Therefore, $Meselson$ and $Stahl$ had no contribution to the development of the double-helix model.

Who amongst the following scientists had no contribution in the development of the double-helix model for the structure of $DNA$?
