The correct option is D interfere
To “meddle” means to interfere in something that is not one's concern.
Option D is the correct answer because “to interfere” means to intervene in a situation without intervention, hence it is the correct answer.
Option A is incorrect because “intercede” means to intervene on behalf of someone else, which is not the exact meaning of meddle, hence incorrect.
Option B is incorrect because to “impose” means you force upon someone a rule or decision, which is incorrect because it is not the same answer intervening.
Option C is incorrect because “cross” means to pass in an opposing or different direction, which is not the same as meddling or intervening hence it is incorrect.
