Explanation

Option A, "boring", is the only word that does not match the regex b.*d and therefore passes through unblocked. The pattern requires a b followed by any characters, then a d - "boring" contains a b but has no d anywhere in the word, so the filter never triggers.

Why the distractors are blocked:

• B ("Bad"): In firewall content filters, regex matching is typically case-insensitive. B matches b, and the word ends in d → matches b.*d → blocked.
• C ("Beside"): B matches b, and there is a d later in the word (besid-e) → matches b.*d → blocked.
• D ("abroad"): The substring b...d is clearly present (b-r-o-a-d) → matches b.*d → blocked.

Memory tip: Think of b.*d as a trap that snaps shut the moment it finds any d after a b. "Boring" escapes because it never gives the trap a d to grab onto - no d, no match, no block.
