A. FSOs should have backstops to prevent overshoot to neighboring office windows or rooftops.

Explanation:

FSO means a floating storage and offloading vessel.  It is a simplified version of a floating production, storage, and offloading (FPSO) unit.  FSO vessels are mainly floating vessels used by the offshore oil and gas industry for the storage of oil.  Unlike the more advanced FPSO it cannot be used for the production and processing of hydrocarbons, and storage of oil.  Since FSOs are installed offshore storage and offloading vessels, there is no need to harden the infrastructure by having "backstops to prevent overshooting to neighboring office windows or rooftops."
