Answer:
D. Reckless
Step-by-step explanation:
To be reckless is to be heedless of danger or the consequences of one's actions; rash or impetuous (Wordreference dictionary).
You can consider how reckless was Mr. White according to this cite:
"He darted around the table, pursued by the maligned Mrs. White armed with an antimacassar.
Mr. White took the paw from his pocket and eyed it dubiously. "I don't know what to wish for, and that's a fact," he said slowly. "It seems to me I've got all I want." (Jacobs, The Monkey's Paw)
