Along hot spots, vast amounts of basaltic lava can flow from fissures, forming:

The answer would be flood basalt. This is the outcome of a huge volcanic eruption or sequence of eruptions that covers large expanses of land or the ocean floor with basalt lava. The development and effects of a flood basalt hinge on a variety of factors, like latitude, continental configuration, rate, volume, period of eruption, the preexisting climate state, style and location, and the biota flexibility to alteration.

any one of the statements could be an accurate comparison. but the statement that would define the correct choice and seal the deal is not even on the list:

"the visibilities of vector-x and vector-y in the drawing provided with the question are identical and nonexistent."

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )
