    It has to be basalt. Though composition of gabbro and basalt may confused you. But look at the scale of the grains present. For a fine grained rock or aphanitic rock the grain size is nearly equal to 1mm or less than that. So as per scale of the grain size given, it has to be Basalt not gabbro.
