使用gsub。

snt <-  "When giving a Gift, it is [Best] to"

alt <- list('better', 'ideal', 'moste effective')

lapply(alt, \(x) gsub('\\[Best\\]', x, sentence))
# [[1]]
# [1] "When giving a Gift, it is better to"
# 
# [[2]]
# [1] "When giving a Gift, it is ideal to"
# 
# [[3]]
# [1] "When giving a Gift, it is moste effective to"
