Based on the knowledge about radioactive elements, the decay of radioactive elements such as uranium creates heat especially in Earth's crust, where these elements are abundant.
<h3>What are radioactive elements?</h3>
Radioactive elements are elements which undergo spontaneous decay of their nucleus and in the process produce elements with smaller atomic masses with the release of radiation and heat.
Examples of radioactive elements include uranium and radium.
Therefore, the decay of radioactive elements such as uranium creates heat especially in Earth's crust, where these elements are abundant.

Answer:
A. are brought from the mantle to the surface in magma that hardens into kimberlite
Explanation:
Diamonds are brought to the surface from the mantle in a magma that is known as the kimberlite. This kimberlites is rich in gases and it is an igneous rock that has the following minerals,olivine, phlogophite, serpentine etc.
The origination of diamonds in the mantle happens as carbon transformation occurs due to heat and pressure occurs. The kimberlite pipes and what brings the diamonds to the surface
The seismic focus is the point in the earth's crust where an earthquake originates from.
