Step1: Recall parallel - plane concept

In a rectangular prism, opposite faces are parallel planes.

Step2: Analyze each option

• For "BCD and FGH": BCD is a triangular - like face and FGH is a face. They are not opposite faces.
• For "BEF and FGH": BEF and FGH are adjacent faces, not parallel.
• For "DEH and CDG": DEH and CDG are adjacent faces, not parallel.
• For "BCF and FGH": In a rectangular prism, BCF and FGH are opposite faces. Opposite faces of a rectangular prism are parallel planes.

BCF and FGH
