When hanging off drill pipe in emergency situations aboard a MODU, the preferred location of the drill bit is __________.

Correct Answer: Option B — no deeper than the shoe of the last casing set

During emergency hang-off operations, the drill bit must be positioned no deeper than the shoe of the last casing set. This ensures that if the well kicks or the formation collapses, the drill string remains clear of the open hole section, protecting the integrity of the wellbore and the drill string.
