Adding 0.050 moles of NaOH will destroy the buffer by reacting with the acidic component of the buffer, HC₂H₃O₂, to form water and the salt NaC₂H₃O₂, which is not a component of the original buffer solution. This will disrupt the pH of the solution and make it more basic, destroying the buffer capacity. The other options either add more of the buffer components (option C and D) or introduce a strong acid (option B), which will not destroy the buffer. Option E is not correct, as one of the options (option A) will destroy the buffer.
