Divergent boundaries often begin as triple junctions composed of three rift "arms" at ~120° apart (which may or may not evolve into divergent boundaries). Knowing that rifts (red lines) generally open perpendicular to the rift (or sub-parallel to the light blue transform faults), which of the statements below about this area is incorrect?

a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction ANSWER
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast
