== == Some basalts may be older than some sandstones, but ages of sandstones and basalts vary tremendously. Some sandstones are therefore older than some basalts. Oceanic basalts are rarely over 200 million years in age.
The sandstone layer is older than the basalt. The older rock cannot be on top of the younger rock. The sandstone and the basalt (or basalt dike) are both deposited at the same depth.
Basalt. Shale, Sandstone, and Limestone are all sedimentary rocks
Sandstone is the odd one out as it is a sedimentary rock, as opposed to granite and basalt which are respectively felsic and mafic igneous rocks.
Basalt is eroded to sand by wind and rain. The sand accumulates in ocean sediment and experiences great pressures over time. After a sufficiently long time, and uplift reveals what had been sand and has become sandstone.
Coal is the only rock on the list which is an organic / biogenic sedimentary rock. Sandstone and conglomerate are both clastic sedimentary rocks and basalt is a mafic extrusive igneous rock.

If the sandstone is below the basalt layer, it is older. Though caution is advised, to make sure it is really a basalt layer and not an intrusion of gabbro. Other indicators that the sandstone is older is evidence of alteration to the sandstone where the two meet (called a "baked contact") and pieces of sandstone being found in the the basalt.

Quartzite is metamorphosed quartz sandstone. Basalt is an extrusive igneous rock.

Basalt does not belong; it is an igneous rock and all the rest of them are sedimentary.
