Official USCG Answer & Rule Citation
Correct Answer: Option B — 1.64 feet
New longitudinal center of gravity (LCG) is found by taking the algebraic sum of initial and removed longitudinal moments divided by the new total displacement, resulting in 1.64 feet per standard weight-shift and removal stability equations.
