Question Analysis
This question assesses understanding of lateral surface area in pyramids with non-square bases (hexagonal).

Key Concept Explanation
The lateral surface area (LSA) of a regular pyramid is calculated by:
Perimeter of the base × slant height ÷ 2
For a regular hexagon, the perimeter is 6 × side length.

Step-by-step explanation
Perimeter of base = 6 × 4 cm = 24 cm
LSA = (24 × 7) ÷ 2 = 84 cm²
