<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>

Answer: A. mandibular lingual and maxillary facial.
Explanation:
In dentistry, the intercuspation can be defined as the occlusal position of the mandible. In this the cusps of teeth of both arches actually interpose with the cusps of the teeth belonging to the opposing arch. This position of teeth is called as centric occlusion.
According to given position of teeth the maxillary and mandibular incisors are in crossbite state thus the intercuspation will occur maximum at the mandibular facial and mandibular lingual.
