Explanation

Seismic enclosures are purpose-built to secure and stabilize equipment during earthquake activity, using reinforced frames, anti-tip mechanisms, and mounting systems that absorb and resist the shock and vibration of seismic events. Options B, C, and D each describe real categories of protective enclosures, but different ones: liquid protection is the role of waterproof or splash-resistant (IP-rated) enclosures; dusty environment protection also falls under IP-rated sealed enclosures; and fire or heat protection is the function of fire-rated or thermally insulated cabinets. The key to this question is the word "seismic" itself, which is the scientific term for earthquake-related activity.

Memory tip: Seismic = seismology = the study of earthquakes. The enclosure type is named directly after the hazard it guards against, so let the vocabulary do the work for you.
