BThe oil sludge residue may be burned in a boiler OR engine, AND it may be burned without restriction in terms of vessel location.
CThe oil sludge residue may be burned in a boiler only AND may be burned only in unrestricted waters (other than in port, in harbors, or estuaries).
DThe oil sludge residue may be burned in a boiler only AND may be burned without restriction in terms of vessel location.
AI Explanation
The correct answer is A. According to the MARPOL Annex VI regulations, the permissible alternative to burning oil residue sludge in an appropriate incinerator is to burn it in a boiler or engine, but only in unrestricted waters (other than in port, in harbors, or estuaries). This is because the regulations aim to limit the environmental impact of sludge disposal, and burning in restricted waters could lead to air pollution and other issues. The other options are incorrect because they either allow burning without any location restrictions (B) or only allow burning in a boiler (C and D), which is more restrictive than the actual MARPOL regulations.
