The correct answer is: A. metamorphic rocks.
Metamorphic rocks are formed when existing rocks are subjected to heat and pressure. This can happen when rocks are buried deep underground, or when they are involved in mountain building. The heat and pressure cause the minerals in the rocks to recrystallize, forming new minerals with stronger bonds.
Igneous rocks are formed when magma or lava cools and solidifies. Magma is molten rock that is found beneath the Earth’s surface. Lava is magma that has reached the Earth’s surface. When magma or lava cools, the minerals in it crystallize. The bonds between the minerals in igneous rocks are strong, but not as strong as the bonds in metamorphic rocks.
Sedimentary rocks are formed when pieces of other rocks are deposited and compacted together. These pieces of rock can be pieces of igneous rocks, metamorphic rocks, or even other sedimentary rocks. Over time, the pieces of rock are cemented together by minerals, and the sedimentary rock is formed. The bonds between the particles in sedimentary rocks are not as strong as the bonds in igneous or metamorphic rocks.
In conclusion, the strongest bonds exist between the particles found within metamorphic rocks.
