B. phaneritic

The igneous rock, gabbro, most like formed from the molten material that cooled slowly, deep underground (4).

The rock underneath the basalt takes longer to cool and the grain is not as fine as Basalt's grain. This is because the lava cools slower; therefore, larger crystals have time to develop.
