A1 and 3 only
B1, 3 and 4
C2 and 4
D3 and 4 only

Explanation

Springs emerge where groundwater finds an outlet: well-jointed rocks let water percolate and reappear (1), karst topography with its solution channels and caverns produces abundant springs (3), and tilted strata can bring an aquifer to the surface along its dip (4). Arid areas with underlying rocks (2) lack the recharge and permeable pathways needed for springs. Hence 1, 3 and 4 are correct.
