The correct answer is: They usually have high melting points.
Transition metals are a group of elements that are found in the middle of the periodic table. They possess several common properties, but the one they share in this case is having high melting points.
To arrive at this answer, you can eliminate the other three options. You can determine this by comparing them to the general characteristics of transition metals. Transition metals are typically dense, rather than having low densities. They are also known for their hardness and strength, so they are not usually very soft. While they can be reactive, their reactivity varies depending on the specific transition metal. Lastly, transition metals typically have high melting points due to the strong metallic bonding between their atoms. Therefore, the property common to transition metals is that they usually have high melting points.
