Answer 1

Use separate_rows assuming the columns have equal number of elements in each row which are comma separated

library(tidyr)
separate_rows(df1, c(var_1, Var_2), sep=",")

-output

# A tibble: 4 × 2
  var_1 Var_2
  <chr> <chr>
1 a     c    
2 b     d    
3 e     g    
4 f     h    

data

df1 <- structure(list(var_1 = c("a,b", "e,f"), Var_2 = c("c,d", "g,h"
)), class = "data.frame", row.names = c(NA, -2L))
