Antonym of ESTABLISH

disrupt
uproot
corrode
negate

The correct answer is: B. uproot

An antonym is a word that means the opposite of another word. In this case, the word “establish” means to set up or found something, while the word “uproot” means to pull something up by the roots. So, the opposite of “establish” would be something that destroys or removes something from its foundation.

The other options are not opposites of “establish.” “Disrupt” means to disturb or interrupt something, but it does not necessarily mean to destroy it. “Corrode” means to eat away at something, but it does not necessarily mean to remove it from its foundation. “Negate” means to deny or contradict something, but it does not necessarily mean to destroy it.

In conclusion, the correct answer is “uproot.”
