Choose the correct antonym being the most opposite meaning. Eradicate

Concept: An antonym question asks for the option whose meaning is most directly OPPOSITE to the given word — not a synonym or a word that merely shares its general theme. Fix the exact sense of the given word first, then test every option against that sense; discard any option that restates or reinforces the same meaning.

Application: "Eradicate" means to destroy or remove something completely — to root it out so nothing remains. "Uproot", "Eliminate", and "Dismantle" all describe removing, ending, or taking something apart, so each stays in the same 'destroy/remove' sense as "Eradicate" rather than reversing it. "Implant" means to fix, insert, or establish something firmly in place — the reverse action of removing it entirely — so it is the option whose meaning is most opposite to "Eradicate".

• "Uproot" shares Eradicate's sense of destroying by pulling out completely, so it reinforces the stem rather than opposing it.

• "Eliminate" also means to remove or get rid of something fully, again matching rather than reversing the stem's sense.

• "Dismantle" means to take a structure apart piece by piece, which is still an act of destruction/removal, not its opposite.

Result: Because the required antonym must reverse the 'destroy/remove completely' sense of "Eradicate" into a 'fix/establish' sense, "Implant" is the correct answer.
