I think D) grep 06 birthdays | grep 05 is the correct answer because it specifically looks for birthdays in May and June.

But wouldn't option C) grep '[0-9]*-0[56]-' birthdays also work?

Hold up, are we sure there aren't any people with birthdays on the 31st of June? Better cover all our bases with D, just to be safe.

Hmm, I'm leaning towards C. It's the most straightforward approach, and who doesn't love a good old-fashioned regular expression?

D seems a bit convoluted. Why use two greps when you can do it in one shot with C? Efficiency is key, folks.

Option C looks good to me. It matches the YYYY-MM-DD format and specifically searches for 05 or 06 in the month field.
