Which quotation from the passage best develops the central idea that some ghosts are friendly? "My cheerful spirits returned at once, and in sympathy with them the gas turned up brightly again."

"... I felt a faint gust of air fan my cheek, and presently was conscious of a huge, cloudy presence before me."

"...an arm appeared, then legs, then a body, and last a great sad face looked out of the vapour."

"I slowly raised myself toward a sitting posture, and my face came into contact with a clammy hand!"
