Concept:Identify errors in underlined parts of a sentence.
Explanation:The error is in part (a).
The phrase "the task is from done" uses the wrong preposition.
The correct expression is "far from done", meaning the task is not at all complete.
Thus, replace 'from' with 'far'.
Part (b) "particularly in ensuring equity in" is grammatically correct.
Part (c) "the distribution of quality education" is also correct.
Option (d) "No error" is therefore incorrect.
The correct response is (a).
