B Correct answer
Explanation

Karst topography, formed by chemical dissolution of soluble rocks like limestone, is indeed associated with blind valleys (valleys that terminate abruptly where a stream disappears underground). Aeolian (wind-related) topography is associated with ventifacts - rocks faceted and polished by wind-blown sand. Periglacial topography (areas adjacent to ice sheets) is associated with pingos - ice mounds formed by freezing water. However, humid topography is not associated with 'stone lattice' - this appears to be an incorrect or made-up term. Therefore, pairs 1, 3, and 4 are correct.
