In the Parable of the Talents (Matthew 25:14-30), what is the *implied* sin of the servant who buried his talent, beyond simply not increasing it?

A He directly disobeyed his master's explicit command. B He demonstrated a lack of trust in his master's judgment and character. C He embezzled the talent for personal gain, later returning it to avoid detection. D He secretly desired the master's position and resented being given a lesser responsibility.
