Answer:
The correct answer is extrusion of magma.
Explanation:
Extrusion of magma is not a type of sedimentary rocks, but a type of igneous rock.
<u>Sedimentary rocks</u> are mainly composed of <u>sediments deposited from air or water</u>, while igneous rocks make it from molten magma.
The process of formation of extrusive rocks is carried out when the hot magma coming from inside a volcano, it comes to the surface through cracks, and when it reaches the surface of the earth it cools quickly, hardening and forming this type of rocks
.
It can also happen that on its way out, magma melts other rocks, and when all this cools it forms this new type of rocks.
On the other hand, sedimentary rocks are formed by small particles of minerals or other rocks that go through processes in which a rock is broken, transported by ice, water or wind and after several processes it becomes a new rock.

For seismograph A, the lag time is
5 minutes (difference between 6:10 and 6:05)
For seismograph B, the lag time is
15 minutes (difference between 6:25 and 6:10)
Assuming that earthquake waves have a constant velocity during the earthquake, then the seismograph with the shorter lag time is closer to the epicenter. So,
Seismograph is closes to the earthquake's epicenter
