Which quotation from the passage best develops the central idea that some ghosts are friendly?

"All my misery vanished--for a child might know that no harm could come with that benignant countenance."
"I sat down and fell into a dreamy contemplation of that great footprint in the ashes."
"I heard, at intervals, stealthy footsteps creeping in and out among the corridors, and up and down the stairs."
"Then I became conscious that my chamber was invaded--that I was not alone."
