Selected Answer: B
The effect of the `egrep` command when the `-v` option is used is: B. It only outputs non-matching lines. The `-v` option in `egrep` (or `grep -E`) inverts the matching behavior, meaning it only displays lines that do not match the specified pattern or regular expression. It filters out and shows lines that do not contain the pattern.
