• A. break down
• B. break
• C. crumble
• D. dismantle

Hint:

Phrasal verbs often carry idiomatic meanings not captured by the root verb.

Answer 1

The Correct Option is A

The correct phrasal verb for removing abstract or structural barriers is “break down.” “Break” is vague, and “crumble” and “dismantle” are less idiomatic here.
