The command that replaces each occurrence of 'bob' in the file `letter` with 'Bob' and writes the result to the file `newletter` is:
D. `sed 's/bob/Bob/g' letter > newletter`
The `sed` command with the `'s/bob/Bob/g'` expression is used for global substitution, meaning it replaces all occurrences of 'bob' with 'Bob' in the file. The output is then redirected to the file `newletter`.
