Limestone should not be porous because the water may pass through the rock mass and thus whole rock mass will become weak and will collapse. On the other hand, if limestones are non-porous and thickly bedded, water will infiltrate through joints resulting into effective corrosion of the limestone.

Introduction:
Karstic topography refers to a landscape formed by the dissolution of soluble rocks such as limestone, dolomite, or gypsum. It is characterized by features such as sinkholes, caves, underground drainage systems, and disappearing streams. Several conditions are necessary for the development of true Karstic topography.
Explanation:
Condition a) The limestone must be massive, thickly-bedded, well jointed:
This condition favors the development of Karstic topography because the presence of massive, thickly-bedded limestone provides a large volume of soluble rock for chemical weathering and dissolution processes to occur. Well-jointed limestone also facilitates the movement of water and the formation of underground drainage systems.
Condition b) Limestone should be porous and permeable:
Contrary to the other options, this condition does not favor the development of true Karstic topography. Porosity and permeability refer to the ability of a rock to hold and transmit fluids, respectively. While porosity is essential for the storage of water, it is not a prerequisite for the formation of Karstic topography. The dissolution of soluble rocks primarily occurs through chemical weathering processes rather than the movement of fluids. Therefore, the presence or absence of porosity and permeability does not directly influence the development of Karstic topography.
Condition c) The positions of limestone should be above groundwater table:
This condition is crucial for the development of Karstic topography. If the limestone is below the groundwater table, it will be continuously saturated with water, inhibiting the dissolution processes. When limestone is above the groundwater table, it allows for the circulation of air and water, enabling chemical weathering and dissolution to take place.
Condition d) The limestone should be highly folded, fractured, or faulted:
Highly folded, fractured, or faulted limestone enhances the development of Karstic topography. These structural features provide pathways for water to infiltrate and flow through the rock. The increased surface area resulting from folding, fracturing, or faulting also promotes the dissolution of the limestone.
Conclusion:
Among the given conditions, the one that does not favor the development of true Karstic topography is the requirement for limestone to be porous and permeable. While the other conditions, such as the limestone being massive, well jointed, and highly folded/fractured/faulted, along with its position above the groundwater table, are all favorable for the formation of Karstic topography.
