(D) those with poor power
EXPLANATIONS BELOW
Concept note-1: -To consecrate means to declare something holy and hallow is its synonym. Lincoln is saying that the ground cannot be declared holy, because: The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or detract.
Concept note-2: -Why can’t “we” consecrate the cemetery? The world will little note nor long remember what we say here; but it can never forget what they did here. It is for us, the living, rather, to be dedicated, here, to the unfinished work that they have thus far so nobly carried on.
